I had repeated I/O-errors while having /home on the ssd, with kernel
2.6.32-tuxonice and 2.6.32-tuxonice-r1 ... now I use my hdd-based /home
again and the errors are gone (so far, maybe the re-occur after sending
this mail, you know ...).
The home-related I/O-errors still happened after poweroff, the "fsck -f"
showed no errors.

My root-fs is still on the ssd, root-fs AND home-fs are ext4 ...
Just for the records and discussion ...
