Hi,
with a self-compiled linux-3.4-rc4 I am seeing this bugs/failures/warnings:
[ 0.241572] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored
[ 0.279385] pci0000:00: ACPI _OSC request failed (AE_ERROR),
returned control mask: 0x1d
[ 0.293699] system 00:0a: Plug and Play ACPI device, IDs PNP0c02 (active)
[ 0.294032] ACPI Error: Invalid/unsupported resource descriptor:
Type 0x00 (20120320/utresrc-650)
[ 0.294037] pnp 00:0b: can't evaluate _CRS: 12311
The same outputs I have seen also with an unsupported drm-intel-next
kernel from Ubuntu/PPA archives [1].
What does ist mean? Is it harmless? Buggy firmware/bios?
Do you need more background infos (dmesg, kernel-config, etc.)?
Regards,
