Comment 4 for bug 324031

I suspend/resume often. It _usually_ works. In Hardy, it was close to 100% reliable; in Intrepid, it usually worked, but sometimes I had to hard-reboot after resume (ie with the blank screen). In Jaunty it has been fairly reliable but occasionally the kernel crashes and I have to hard reboot. This morning after I resumed X restarted (ie I had to log in again after resume and I lost the apps that were running when I suspended) - but this is the first time I've seen that.

I have put SUSPEND_MODULES="nvidia" in the file /etc/pm/config.d/modules in case that is relevant. In the past, nvidia recommended this.

It's nothing to do with the battery running out - I just select suspend from the System / Shut Down menu option and then restart the PC at some point later.

On the occasions where it crashes after resume, I can't select VT-1 or even ssh from another machine.

The only other observation I have is that the crashes usually (but not always) happen after I've physically moved the laptop between my home office and the work office. This usually means I've suspended, then unplugged the external monitor I have at home, then resumed in the office without it plugged in. Or vice versa.
