Debian 64-bit an Dell Vostro 3750 - freezes sometimes with message [Firmware Bug] ACPI(PEGP) dedefines _DOD but not _DOS
Hi,
I have strange problem with my Dell Vostro 3750 (two graphic adapters:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: nVidia Corporation Device 0df5 (rev a1)
)
When booting the Linux OS (tried kernel 3.0.0 and 3.0.1) I often get system frozen during the boot.
The last line on the screen states:
[Firmware Bug] ACPI(PEGP) defines _DOD but not _DOS
The strangest thing is that connecting of any device to the USB jack highly increases the probability of that problem.
Without any USB devices probability of success is almost 100%.
With one USB device - GSM/UMTS modem - boot succeeds in ca 50%
When I additionally connect the UGM-96 guitar sound card - boot almost never completes.
Both devices work perfectly when plugged in after boot.
It seems, that there is a race condition during the boot, and connection of USB device increases the time window in which the problem may appear.
I saw similar problem reported by others (it is enough to enter "[Firmware Bug] ACPI(PEGP) defines _DOD but not _DOS" in google) but no good solution (booting with acpi=off is not a good idea when
machine has 4 HT cores and usually at least 3 of them are really hard working ;-) ).
Most reports mention the Dell Vostro 3750 - so maybe the problem is associated with a bug in the BIOS (I use the newest version A05 - downloaded from Dell and flashed. Before the BIOS upgrade
situation was similar <I don't remeber what was the BIOS version initially...>).
Has anybody faced and cured the problem?
