Well, I've got two notebooks: one suffers on it, the other not. The core
differences between these two notebooks:

32 bit vs 64 bit
single threaded vs multi threaded (intel Core i5)

The single threaded notebook does not suffer on this problem, the multi
threaded does. The problem doesn't happen every time. I think it's
dependent from the files affected. I even saw a broken
~/.xsession-errors file. It contained a lot of 0x00 "characters" in one row.

If this happens to a library or binary, which is used for resuming,
resuming won't work, too. That is to say the next problem I suffer on:
resuming - even s2disk just doesn't work at all some times.


Kind regards,
