Been using my A150 for a while and in the last few months noticed that it periodically "hangs" i.e. freezes with no response from any input (I need to hold the power button down for 5 secs to reset. This happens aprox every 2-3 hrs. I'm running UNR 9.04, but I think I noticed the same behaviour when I installed Crunchbang. I'm sure the log files could help, but relatively new to this Linux game, so not sure which is relevant. Any help/suggestions appreciated.
