[Launchpad Bug Tracker <339336@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

System is:

Description:	Ubuntu jaunty (development branch)
Release:	9.04

I think the problem is with the kernel. Why:

Both Ubuntu and Kubuntu (9.04) behave the same way; after restart, they
both say they want to report a kernel bug. In case of Ubuntu the
reporting tool crashed while trying to report it (I commented on the
appropriate bug) and in the case of Kubuntu the crash reporter app
stopped appearing after I got my Internet connection, so I couldn't
report it.

The laptop is equipped with an Athlon XP 2500+ (Barton), chipset VIA
KM400, graphics Radeon 9200, sound VIA 8235.

What I expected to happen:

Computer resumes.

What happens:

Complete hang. Usually I see "checkerboard corruption" on the screen (I
often see this, e.g. when the computer starts X during boot, or in prior
versions of Ubuntu, when resuming from standby. Usually stays on the
screen for about 1-2 secs and then is correctly redrawn), but sometimes
the screen remains completely black (not even the backlight comes on)
and once, when booting from the LiveCD, I saw the cursor and could move
it for a bit, and then it froze.

The hang happens with and without compositing effects enabled.

Suspend works correctly on 8.04 and I don't remember it not working on
previous versions. Did not try 8.10.

Following instructions from
https://wiki.ubuntu.com/DebuggingKernelSuspend I did not get any useful
info from dmesg. But maybe someone will, so I'm attaching it.

Please advise what other info I could provide. Thank you.
