This may not help things though.
It has helped and the laptop is able to suspend with the serial cable
attached (further than before). It now panics on the first resume with
the following (gdb output at bottom).
I think the serial cable is masking the problem as without it I can
suspend/resume once and it only panics on the second resume. I guess I
need the serail working to see that panic anyway.

ACPI and a Toshiba Tecra 8000
Hi, I have -current on my laptop as of yesterdays sources and my suspending isnt working quite right. The first time I suspend (S3) it works and comes back to life, but the second time the laptop reboots when it resumes. I have now build a new kernel with debuging/ddb and hooked up a serial cable. When I boot to the comconsole and try to suspend it panics straight away with the following.
