Hardware: Fujitsu Lifebook P-2040, TM5800 800 MHz processor
2.6.21: Closing the lid causes APM suspend. Opening it resumes just fine.
2.6.22-rc5/-rc6: On resume, backlight comes on, but system is otherwise
frozen. Nothing happens until I hold the power button to force
a power off.
I'm trying to bisect, but there's a large range of commits which crash
on boot in init_transmeta, which is slowing me down.
However, I did manage to find a kernel version that gives an error
message instead of a blank screen, which might be useful. I can even
switch VTs and type into the shell afterwards, but actually trying to do
anything hangs. Which includes anything like run a command to capture
this to a file or another machine on the network, even if I took care
to cache the necessary executables and libraries before suspending.
So the following is transcribed by hand.
