Description Martin Mokrejs 2006-10-08 13:57:01 UTC 
Most recent kernel where this bug did not occur: 2.6.17.11
Distribution: Gentoo
Hardware Environment: ASUS L3C/S laptop
Software Environment:
Problem Description:

I googled out this has been reported in -mm kernel series, but that was some
kernel panic. I don't get panic, the machine "works" but I have observed this
message in the logs.

acpi_processor-0742 [00] processor_preregister_: Error while parsing _PSD domain
information. Assuming no coordination
acpi-cpufreq: CPU0 - ACPI performance management activated.

Comment 3 Robert Moore 2006-10-11 10:50:51 UTC 
Looks like there is no _PSD in the DSDT, causing this message from 
processor_perflib.c

Probably overkill to emit this message for the no _PSD case?
Comment 4 Venkatesh Pallipadi 2006-10-11 14:33:33 UTC 
Yes. This message is a false alarm and should be removed in no _PSD case.

Will send a patch to remove this.
Comment 5 Martin Mokrejs 2006-11-28 09:35:53 UTC 
Still appears with linux-2.6.19-rc6-git10
Comment 6 Zhang Rui 2006-12-13 23:16:50 UTC 
Hi, Venki
Is it OK to be a ACPI_DB_INFO when no _PSD available?
And others remain the same.
I'll generate a patch after -rc1 comes out :)
Comment 7 Venkatesh Pallipadi 2006-12-14 04:47:59 UTC 
Rui,
Just y'day I sent a patch to Len to  remove this message altogether :).
Comment 8 Venkatesh Pallipadi 2007-01-03 18:30:35 UTC 
This should be fixed in latest 2.6.20-rc release. Closing.
Comment 9 Martin Mokrejs 2007-01-10 02:05:48 UTC 
I still see the message with 2.6.20-rc4-git2. :(
