Subject: Hang on suspend

I'm getting a hang at suspend on 2.6.25-rc2. Booting with
no_console_suspend let me catch the error, which I photographed and
transcribed (hopefully without error) below.

This is a Lenovo Thinkpad T43p.

I've attached my config and a partial dmesg (this machine generates a
lot of messages at boot, and overfills the buffer before klogd gets to
it).
