N270 optimized kernel

Just wanted to say thanks for the custom kernel, I am using it now. I also installed lxde which is working out good so far.

 

Just in case anyone has missed the Master Kernel Thread on the Ubuntu forums, here it is.

A great walkthrough to compiling your own kernel from the newest sources on Ubuntu. Also see Kernelcheck link on the thread as well. It takes all the steps in the guide and packages them in a easy to use GUI. Makes building your own kernel amazingly easy.

 

Is anyone else having issues with a wired network connection with this kernel? Ive just done a fresh install and tweak of intrepid and the only things not working are sound after suspend and wired ethernet. The sound looks like its fixable (see here) but it cant be done with the files in this thread. The wired connection is a bit odd though - it doesnt seem to be able to tell if a cable is connected or not. Maybe connected to this in dmesg: "r8169 0000:02:00.0 unknown MAC (27a00000)", anyone had similar problems?

Edit: After playing around a little, the wired connection problem mainly happens after a reboot. It will generally work after power on, either leaving the cable in at boot or connecting afterwards is fine, but after reboot theres much less chance of it working properly...

 

Good Job this kernel

But I don't use it because there is problem to compile anything on the 221008 kernel... Can't compile madwifi, can't compile new alsa-drivers....

I also have the ETH0 problem, no problem on generic kernel

So i kept my generic kernel and compiled My RNDIS/MADWIFI/HSO and ALSAMIXER and everything work I hav also Hibernate that working with s2disk (apt-get install uswsusp)

So that's good

I kept an eye on this topic perhaps will it be the ultimate kernel

 

Nice job with this kernel!

However im having some errors with the card readers. When i insert a sd-card, it gets automounted, but when i try to eject it from the desktop i get the following error:
"/usr/bin/eject: unable to eject, last error: Inappropriate ioctl for device."
sd-card gets unmounted, but the icon stays on desktop. If i try to enter it from thunar, it gets mounted again. Any ideas how to fix this? Oh, im using the 102208-kernel, but had this problem already with the generic kernel.

 

Does it suspend/resume works with /home on left SDHC????

 

Yes, the 102208 kernel works correctly with /home on the SDHC. If you use the right-hand SD slot, you might want to modify /etc/fstab so that it uses UUIDs to avoid any confusion on resume or boot. For example, here's mine (your UUIDs will be different):

Code:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
# /dev/sda1
UUID=6b25c864-dae3-4b56-89ac-2c6cb4031ae5 /               ext2    noatime,errors=remount-ro 0       1
# /dev/sda5
#/dev/sdb1       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0
#/dev/scd0       /media/cdrom1   udf,iso9660 user,noauto,exec,utf8 0       0
tmpfs		/tmp		tmpfs		defaults		0	0
tmpfs		/var/tmp		tmpfs		defaults		00
tmpfs		/var/log		tmpfs		defaults		00
#/dev/mmcblk0  
UUID=986fb851-13fb-4aa6-9de0-58450d012134	/home	 	ext2 	rw 	0 	0

I don't typically use the right-hand slot, so I don't load pciehp in /etc/modules.

I'll take a look at some of the other issues in the thread...might be time to spin a new kernel.

yeh suspend/resume works fine, but i dont have login sound ...

 

That is because ALSA is compiled into the kernel with power saving enabled., It takes a couple seconds for sound to kick in, and by that time the login sound is over.

 

Can it be fixed?

 

Recompile the kernel with the powersave option turned off. Your battery life will suffer though.

Adding this line to your /etc/rc.local may work.

Code:

echo 0 > /sys/module/snd_hda_intel/parameters/power_save

 

Hi all

I installed this kernel as instructed. Overall running feels smoother, so my thanks to Perry for the great job.

There are a few things that are grinding away at me however:

When i boot, i now see the following message flicker:

Code:

modprobe: WARNING: /etc/modprobe.d/blacklist line 48:ignoring bad line starting with 'ath_pci'

modprobe: FATAL: Could not load /lib/modules/2.6.27-0.102208/modules.dep: No such file or directory

Line 48 is as follows:

Code:

blacklist ath_pci

Is this error occuring because i am trying to block a module that the kernel knows nothing about?

Also, the following is bugging me a bit:

My welcome noise has the first half chopped off?
I cannot load my Ipaq module anymore? How can i do this please?
I don't want to laod the bluetooth module - can i blackklist this as i've done with my ath_pci module?

Also, Perrry posts a config file with each release - how can i use this please? Will it get my boots down to 15 seconds? Currently im 35 sec to login screen, 40 sec to stable desktop.

Thanks in advance.

 

'Bad line' usually means that there's a syntax error. ath_pci isn't in the kernel, so you can remove the line if you like.

The FATAL that shows up at boot is from initramfs. It's harmless, an artifact of how the initramfs is built. Looks bad, I'll admit

Andysan,

As you see ath_pci is the start of the line. However the start should be like this: blacklist ath_pci
Check your /etc/modprobe.d/blacklist file again.

 

I can use this kernel, i have problems with eth0 lan....how can i solve this? Anyone also have this problem?

 

Hi businessteam,

Yeah, it is blacklist ath_pci - i guess it says starting with "ath_pci" because it is happy with "blacklist" then when it reads "ath_pci" it throws a wobbly because it doesn't know what it is.

Cheers chaps.

 

Anyone able to get rndis to work with this kernel? It works fine with the standard generic kernel but if I follow the same procedures with the optimized kernel it's a no go.

 

No. But there is another kernel in the topic 081022 but another issue ^^ Can't build any module... It failed on Madwifi compilation ^^ For the lightning led!

Edit : Found it http://www.kidpub.com/aspire/linux-kern ... a1.icc.tgz

I think i'll will keep the two kernels on my aspire one

 

I tried out this kernel on 8.10; it boot noticeably faster (desktop in 31 seconds from power on). PowerTOP no longer works though?

 

That's correct. If I'm not mistaken, the kernel needs to have kernel debugging enabled for Powertop. You could build your own kernel to get this functionality back.
