Description Maarten Verwijs 2006-01-22 14:53:19 UTC 
Most recent kernel where this bug did not occur: 2.6.14.4
Distribution: Debian
Hardware Environment: see lspci output
Software Environment: 
Problem Description: Using OSS sound for Intel ICH4 AC'97 causes suspend-to-disk
to hang.

Steps to reproduce:
I'm unsure if you actually need the soundcard. 

I did a make oldconfig of my 2.6.14.4 kernel in order to build a 2.6.15 kernel.
Running that new kernel, swsusp fails. Trying 2.6.16-rc1 gives same result. 

Leaving out the OSS driver for the soundcard, or building it as module, has the
swsusp working fine.
          
I suspend with the following command:
 echo "disk" > /sys/power/state

Bug only applies when drivers are compiled into the kernel. Compiled as
modules, swsusp works just fine.

    
The following lines are the last bits of output before the hangup:

Comment 1 Lee Revell 2006-01-22 16:16:37 UTC 
The OSS drivers are unmaintained, you'll have to use the ALSA driver.
Comment 2 Lee Revell 2006-01-22 16:51:52 UTC 
You can also do a "git bisect" (search LKML archives) to identify the change
that broke it - it's still bad to have a regression, even in a deprecated driver.
Comment 3 Pavel Machek 2006-05-19 02:58:05 UTC 
It would be nice to reproduce with ALSA and/or get that bisection.
