--- Comment #30 from Joaquín Aramendía samsagax@gmail.com --- Created attachment 120321 --> https://bugzilla.kernel.org/attachment.cgi?id=120321&action=edit 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.
