(Get the code!)
Suspend/resume (s&r) from battery causes a freeze always. The only difference is that the blinking CapsLock blinks slower as the CPU frequency is lower ;-). I have even tried pluging in the AC during the hibernation, but without a success.
Actually the ACPI was the first thing that came to my mind. But why would the system freeze always at the point when the "suspend console" (Does it have a proper name?) switches back to either X server or normal console (tty)? The memory corruption of GPU seems more logical, doesn't it? And do you know any way, how this could be debugged?
In case it was a kernel (or X?) bug, who should I contact first? And is there a way how to some kind of kernel oops in such conditions?
Sorry for lots of questions. :-)
