3.6 Regression: kernel NULL pointer dereference in pacpi_set_dmamode

["Anton V. Boyarshinov" <boyarsh@altlinux.org>]

[-- Attachment #1: Type: text/plain, Size: 924 bytes --]

Hello,
We have an early boot crash in 3.6 and 3.6.1 on many machines, using
nvidia chipsets. Boot fails in 1 case to 10 boots or 9 cases in 10 boots, depending on machine.

The head of log, got via serial console(full log attached):
-------------------------------------------
2.672343Ü BUG: unable to handle kernel NULL pointer dereference at 0000000000000010

-------------------------------------------

Disabling on-board IDE controller in BIOS seems to workarownd the problem.

Regards,
Anton
