Description Bastien Nocera 2005-09-26 06:20:09 EDT

On a Dell Inspiron 5160, with the latest BIOS, kernel 2.6.9-11.EL as well as the
later 2.6.9-17.EL crash on startup parsing the DSDT table.
Crash and decompiled DSDT attached below.

This is a regression from 2.6.9-5.x.EL where the bootup worked fine.

The decompiled dsdt. Let me know if you need the original one.

Comment 3 Jason Baron 2005-09-27 14:15:40 EDT

hmmm not sure what went into u1 to cause this...

Comment 4 Bastien Nocera 2005-09-29 06:34:04 EDT

Couldn't find anything really appropriate in the changelogs either. There's been
some ACPI SRAT work, but this shouldn't cause problems on non-NUMA/non-SMP
machines. I'm double-checking that the earlier kernel does indeed work.

Comment 5 Bastien Nocera 2005-09-30 04:56:57 EDT

2.6.9-5.EL works, 2.6.9-11.EL doesn't.

Comment 7 Jim Paradis 2005-10-21 17:29:11 EDT

Devel NAK unless we can get access to the relevant hardware.

Comment 8 Len Brown 2006-01-18 05:18:47 EST

This crash happens when setting _PDC.
There are some common BIOS issues related to _PDC -- namely
that some BIOS assume that PDC will not be invoked more than once.
http://bugzilla.kernel.org/show_bug.cgi?id=5483

This fix is in included in the current ACPI patch and -mm tree,
any possibility of testing a newer kernel?

Comment 11 Bob Johnson 2006-04-11 12:40:02 EDT

This issue is on Red Hat Engineering's list of planned work items 
for the upcoming Red Hat Enterprise Linux 4.4 release.  Engineering 
resources have been assigned and barring unforeseen circumstances, Red 
Hat intends to include this item in the 4.4 release.

backport of the referenced patch for RHEL4

Heres a RHEL4 backport of the referenced patch from the acpi bugzilla.	The
upstream acpi code is significantly different from what is in RHEL4, and so
there may be some problems with it.  I'll post kernels as soon as I have them
built, to my people page.  Please test them as soon as you are able and report
results

Next pass at acpi patch

My last patch had a break for ia64 that I needed to fix up.  This patch builds
for all arches and boots on ia64 and x86 (x86_64 still to be tested)

Comment 17 Neil Horman 2006-04-18 13:28:25 EDT

I've posted an x86 test kernel to my people page:
http://people.redhat.com/nhorman
I don't have the relevant hardware, so someone is going to either have to send
me the hardware to test on, or test this and report results back to me.  Fair
warning, there is about a week before the RHEL4 update freeze, so if testing
results aren't back by then, this bz risks missing the U4 update.

Comment 20 Bastien Nocera 2006-07-26 04:43:48 EDT

We're still waiting for feedback on the test kernel.
