Bug#335934: linux-source-2.6.13: preemptive kernel (sometimes) doesnt suspend to ram

[hramrach@centrum.cz (Debian User)]

Package: linux-source-2.6.13
Version: 2.6.13-1
Severity: normal

*** Please type your report below this line ***

I tried compiling a laptop kernel from the linux-source-2.6.13 2.6.13-1.
Unlike the debian precompiled kernel I tried the most agressive
preemption option. The resulting kernel worked for some time, but then I
installed the xfree synaptics driver.
>From then on, the process writing "mem" to the /sys/power/state would
stay in uninterriptible sleep until system shutdown (did not try to go
to runlevel 2 or something like that). Simply restarting X did not help.
A kernel without preemption or X without synaptics driver works.
The machine is an old Dell laptop with BX chipset.

I am not sure if the Debian patches affect this behavior in any way.
I will try to test with a vanilla kernel later.

Thanks
