Custom kernel

You have to boot with nomodeset on the grub command line unless you're using a KMS aware xserver-xorg-video-intel/libdrm or else you get a black screen because there are no framebuffer drivers outside of the DRM framebuffer. Including a framebuffer driver makes KMS stop working whereas you can just pass nomodeset on the boot options and have it run fine with the old userspace mode setting.

New kernel added to the first post if anyone wants to use it.

 

Code:

Boot from (hd0,0) ext4 c13c8250-ff18-4fed-9edd-58f1bb01f6e8
Starting up ...
Loading, please wait...
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the fight device?)
- Missing modules (cat /proc/modules ls /dev)
ALERT! /dev/disk/by-uuid/c13c8250-ff18-4fed-9edd-58f1bb01f6e8 does not exist. Dropping to a shell!

Busybox v1.10.2 (Ubuntu 1:1.10.2-2ubuntu7) built-in shell (ash)

How to fix it :?:

 

I don't know exactly what is wrong, what happens if you just type exit at the busybox prompt? Let me guess, you're on a SSD model too? It could be a side effect of the AHCI quirk not letting your secondary PATA CFA SSD initalize right. Was that on 2.6.30 or 2.6.29.1?

 

Are you using the solid state SSD version (A110L) or the hard disk version (A150L)?

I am using the A110L and get the same results you do. Sarvatt and I are working to
resolve it. Probably a trivial thing, but elusive.

Has anyone else gotten any of these kernels working? What I'm thinking is it might be the fact that I have all the dev scripts installed so it makes the initrd fine for me (kernel-package uses mkinitramfs/mkinitramfs-kpkg instead of initramfs-tools' update-initramfs) but its having problems for other people. Also there have been alot of updates to grub/initramfs-tools to jaunty in the past few days and some people are having this problem even with the stock kernels

http://ubuntu-virginia.ubuntuforums.org ... ?t=1120858

Only thing I can think of that hasn't been tried is to try adding rootwait to the grub command line. If anything I can just start providing tarballs of the patched source and a script so people can build it themselves. kernel-package is really easy to use and nice for building deb's of kernels on faster machines to use on slower ones. I did a diff of my config vs sickboy's that works for people with SSD's but dont see what could be causing it outside of me having the AHCI patch and me using async scsi init instead of syncronous to speed up boot times. I tried using tuxonice but it completely screwed up my machine, even making my other kernels not boot properly until I pulled the battery. Anyway, sorry about the trouble!

 

Well, looking at the dmsg logs I'm pretty convinced its just the AHCI patch not working for the SSD's. I didn't realize the SSDs in the 110 modules were just ATA emulating compact flash modules and not really SATA drives in the first place. There might be a way to use enable the old IDE and have it use those over sata modules but I don't have a clue about that and don't have anything I could test it with. The AHCI patch is major to me and not something I'd be willing to drop to release it so I'll put a warning in the top post that this is not for 110 models.

 

Updated LATEST in the top post.

 

So..., this kernels dont work on 110L models? Is that correct?

Thanks

 

Didn't work for 2 people so I put the warning, it doesn't hurt anything to try it though

 

ok thanks

 

Hi

Have you managed to get sony memory sticks working with your kernel (assuming that you load the appropriate modules of course)?

 

yep, memory sticks are working fine, just threw in a 4GB to test. the modules should be autoloaded by udev when ya plug it in.

Hi and thanks you for your great work.

I would like to recompile my own kernel starting from your work (i need to build some differents modules), so can you been so kind to tell me if is sufficient to install a "standard" version of gcc 4.4 from ubuntu ppa's in order to get a version of the compiler optimized for atom cpus or if i have also to download and compile gcc from a "special" branch in order to get it?

Thanks in advance
Skumpic

 

you have to install it from a branch on the gcc svn unfortunately
http://gcc.gnu.org/viewcvs/branches/ix86/atom/

 

Really? now thats impressive.
What sort of powersaving config stuff are you running? Just the stuff found in the Wiki?

With my kernel, unr 9.04 and all the power saving stuff from the wiki i was hovering around 8.4W
I have swapped my wifi card for a intel 3945abg and with power saving enabled on this i was getting around 7.7W!! Only problem is with any amount of usage it causes a system lockup and its driving me mad

Now we have pretty much all the hardware working great, power consumption urgently need to be addressed and its good to see you focusing on this.

I dont suppose your kernel has the iwl3945 module in it does it? I wanted to test your kernel but need my wifi!

 

Thanks Sarvatt!!
I will do it later this afternoon. How long it will take to compile gcc from source? I read somewhere it will take up to 7 hours!!!

And then please can you clarify me another point: i saw that you compiled your kernel with acpiphp module built in (CONFIG_HOTPLUG_PCI=y).
I have one of the first aspire 110L (the one with both reader from Jmicron) and i already tried to use acpiphp to enable hotplug in past without success (kernel 2.6.27-2.6.28). Is something changed in this months? Is there any special string that should be passed to grub in order to enable hotplug with acpiphp ? or i still use the "pciehp force" string ?

Thanks in advance for your kindness
Skumpic

 

nothing special needed for acpihp, just an up to date bios possibly. they've pretty much merged acpihp and pciehp now and both do the same thing, pciehp doesn't even get loaded unless you force it. I think it took around 3 hours to compile GCC on a quad amd but it was on my VPS so it's shared. watch out though, compiling a new GCC without screwing up your system is a fun exercise you may want to do it in a virtual machine or something.

I think the only wifi I left out on purpose was ralinks because they dont compile cleanly (STILL.. :lol: ) If you need an option changed on the iwl3945 module let me know and I'll change it for the next release. I dont have one and just used the default options for all the cards except my broadcom.

nothing found in the wiki, its all outdated. I just remove most of the daemons running (even though that removes ubuntu-desktop metapackage) and lower the txpower on my wifi card to 5dBm. I also use the gateway 3103 bios, aka acer's 3309 without the backlight restrictions so yes I get backlight flickering at the lowest setting.

In PHCTray I have both processors undervolted to 22 18 15 15. on the kernel command line I boot with pcie_aspm=force and hda agressive powersavings is set to 5 second timeout in the kernel.

Hmmm. Sorry - but doesn't work for me.

I've just upgraded my BIOS to 3309 and am using your kernel (with acpihp built in). RHS card reader doesn't work at all (and neither does the webcam, but then you aren't loading the video module as is used in the default ubuntu build). Using the earlier builds I get the RHS card reader working with the pciehp module (but no memory stick - bah!) . I'll play around more tomorrow to ensure I'm not doing something wrong.

Wait, you have it booting on an AOA110 or am I mistaken? Thank you for pointing out the thing about uvcvideo though, what a bonehead move! I disabled it by accident when I was removing some DVB interfaces. I've got another build building right now that fixes that based of pre -rc3 with updated i915 and wireless trees merged. I'm at a loss why memory sticks arent working for you though, maybe try adding

options sdhci debug_quirks=1
to /etc/modprobe.d/sdhci.conf to see if it helps.

 

No - it's a 150 (model ZG5). I'll give your suggestion a go and get back to you later.

Thanks
