dmesg after ACPIPHP patch
A follow-up on this issue:
After applying Rafael's patch, the issue with the lockup is still present.
After booting on 3.13rc5 kernel in 'multi-user.target' I managed to get a full
dmesg.
The nouveau driver seems not to handle vgaswitcheroo well. After being disabled
as DSM call mismatch error suggest, it will lock, after a minute or so it
starts printing this messages:
...
[ 123.322051] smeagol kernel: nouveau W[ PFIFO][0000:01:00.0] unknown intr
0x04200000, ch 2
...
Followed by timeout errors:
...
[ 129.302814] smeagol kernel: nouveau E[ PFIFO][0000:01:00.0] channel 2
[DRM] unload timeout
...
[ 149.888549] smeagol kernel: nouveau W[ BARCTL][0000:01:00.0] flush timeout
...
When the laptop finally responded to Ctrl+Alt+Del then a backtrace appeared
regarding acpi hotplug.
And then nouveau is reloaded again! Just before I had to drown my laptop with
the power button.
