    I did just have ath9k type though.
    I'm pretty sure I had one BAM-type shutdown using your custom kernel. I might have to try it again, but I had four ath9k-lockups in one day with it, and have had only one since reverting (forwards) to 3.2.1 (this is unrelated to your efforts of course!)

    Maybe someone could try to install JDownloader and confirm that it increases number of shutdowns drastically?
    I installed it and used it to download an empty 200MB file using four connections over and over. After 20 minutes, no shutdown (3.2.1 with modified DSDT).

    Just a guess, but maybe what you're getting is related to the wireless driver? Then using a program that opens lots of connections could explain why it's more probable for the problem to occur.

    When launching JDownloader and after the laptop shuts down, do you see anything suspicious in /var/log/kern.log, /var/log/messages or /var/log/dmesg.0? Maybe you could try running JDownloader with the USB-Ethernet dongle and see if it changes anything?

    I'm now running a script that uses intel_reg_dumper to take a snapshot of the RC6-related registers every second, I'll look at it when (if?) a shutdown happens.

    After 1 day of full use, vanilla mainline 3.3rc2 with all rc6 optimizations on (but no aspm in the grubline), I still find my system stable. With 8 hours of battery life. Also, the athk9 crash has been a while (but I haven't used any torrent or other heavy network stuff).

    Interesting. Did you have regular shutdowns before upgrading to 3.3rc2? By "vanilla" you mean a kernel.org tarball without the fixed DSDT, correct?

    Could you please give your kernel boot options? Also do you have VT-d disabled in your kernel?

    How do you get 8 hours of battery life?
    I can't even get 4 hours

    Flash off in web browser (I recommend flash block in Mozzilla)
    use power wiki scripts or laptop mode on
    Optimize the socials daemons
    lowers the brightness

    8 hours (sorry for the shock) is of course in idle. Still KDE on, but powermanagement disabled, brightness on low (which is high enough with this screen anyway). Wifi still on, but with the Bssid filled out. This one helped me quite some.

    Kernel options:
    elevator=noop i915.i915_enable_rc6=1 i915.semaphores=1 ipv6.disable=1
    From my experience, the lack of aspm=force might be important.

    VT-d is switched off in the bios.

    And yes, by vanilla kernel I mean the one that is present on the Arch User Repo's as linux-mainline. No DSDT fixes applied.

    Of course, I haven't done this for a long enough time to declare everything officially stable. Karma may still overrule me

    If you manage to go through another day while actively using the PC and still have not shutdowns I'll give it a shot Holding my thumbs for you!

    Hi everyone! Thanks for to everyone helping out and making this laptop more and more usable under Linux!

    I just had a sudden shutdown with the 3.2.0-12.21-ux31 kernel.
    This is the part of var/log/kern.log: (shut down occured at 18:49)

    My /var/log/dmesg.0 seems to be from the 1st of Feb ??? and I dont hav a /var/log/dmesg? What could be the reason for that?

    My Grub line is:
    Code:
    i915.i915_enable_rc6=1 i915.powersave=1 i915.semaphores=1 quiet splash
    Does this make sense to anyone?
