1st: It has to be "Suspend to Ram" thanks for finding the typo. I
corrected the bug report already.

2nd: I just updated my BIOS and the problem seems to be gone. I'll
test a bit more before I can really confirm that, but in two attempts
the laptop woke up without disk errors.
I don't have any options to change the mode of the disk in the BIOS
though. Maybe they changed it without notice.
