Additional info:
when I change flag in  /proc/acpi/video/C098/DOS from 0 to 1 it starts to behave normally but I cannot return from suspend 
when the flag is set to 0 I can suspend/resume normally
Comment 1 RHEL Product and Program Management 2009-03-26 13:08:02 EDT
This request was evaluated by Red Hat Product Management for
inclusion, but this component is not scheduled to be updated in
the current Red Hat Enterprise Linux release. If you would like
this request to be reviewed for the next minor release, ask your
support representative to set the next rhel-x.y flag to "?".
Comment 2 Vladimir Benes 2009-07-27 09:44:09 EDT
I changed /proc/acpi/video/*/DOS from 0 to 1 and now everything (suspend/resume, lid close) works fine.. 
maybe bad component?
Comment 3 Matthew Garrett 2009-09-24 13:06:26 EDT
This is fundamentally a BIOS bug, but it may be possible to work around it. I'll backport a patch and we can see if it helps.
Comment 4 Matthew Garrett 2009-09-28 18:06:40 EDT
Created attachment 362946 [details]
Run ACPI workqueues on CPU 0

This patch should deal with the issue.
Comment 5 Matthew Garrett 2009-10-02 13:23:21 EDT
I'm doing a brew build at https://brewweb.devel.redhat.com/taskinfo?taskID=2014046 .
Comment 7 Matthew Garrett 2009-10-06 13:55:54 EDT
Vladimir, can you test the kernel in the above brew build?
Comment 8 Don Zickus 2009-11-17 16:55:41 EST
in kernel-2.6.18-174.el5
You can download this test kernel from http://people.redhat.com/dzickus/el5
