Hello,
looking for a possible reason for the higher power drain of recent kernels,
as reported in a recent post, I did on my Thinkpad T520 with Opensuse 12.2
and kernel-of-the-day 3.8.2-2-vanilla with
01:00.0 VGA compatible controller: NVIDIA Corporation GF119 [Quadro NVS4200M] (rev a1)
> echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
> rmmod nouveau
This resulted in the rmmod command hanging.
Doing in another console
> echo ON > /sys/kernel/debug/vgaswitcheroo/switch
resulted in a OOPS. I captured the backtrace by photo and can type in
errorprone and send the backtrace on request.
Bye
