MacPro (Please send dmidecode to [email protected])

Hi all,

I just post because my dmesg says so:

ACPI: System BIOS is requesting _OSI(Linux)
ACPI: Please test with "acpi_osi=!Linux" Please send dmidecode to [email protected]

Handle 0x003A, DMI type 0, 24 bytes

If you need more let me know. I mostly looked thru the dmesg because the box shuts down sometimes, randomly. Maybe too hot? But I still investigate.

However, the box (2 Quad-Core CPUs) even awakes from echo mem > /sys/power/state (without graphic though, maybe s2ram posting would fix that - but I do not really care about the graphic as it is indended to be used as server anyway).

Thanks for the dmidecode output.

Do you notice any functional difference when booting with

"acpi_osi=Linux" (default for 2.6.22 and earlier)
vs.
"acpi_osi=!Linux" (default for 2.6.23 and later)

Also, please send me the output from acpidump.

thanks,

Hi Len,

now that was some time between the mails :-)

Unfortunately the 8-core box is sort of running in production and I can not randomly boot kernels.

Passing acpi_os=whatever did not really changed anything back in the days when I tried that. Actually the box is running quite fine (normal server load, no suspend or so) though currently an older 2.6.18+openvz kernel as that was the only openvz patch- set that was stable, all the other openvz patchsets locked up sooner than later ...

If you are still interested in the acpidump I can hunting for it.
