Recent kernels hang on resume

Sat Mar 11 22:12:21 UTC 2006

Just for the record, the recent kernels (2032 and above it would seem),
hang occasionally on resume on my notebook (this is after suspend to
disk with the vanilla kernel code). The last output is:

Stopping tasks: =

I'm attaching the lspci output for hardware reference. Full specs of the
notebook are here:

The suspend to disk/resume first started working with 2.6.15-1.1909_FC5,
when a fix for ATI graphics suspend code was committed to the vanilla
kernel. Things now appear to be broken again. I'm just not sure if
anyone else is seeing this on their hardware, or if it's specific to
this machine.
