I had repeated I/O-errors while having /home on the ssd, with kernel |
| 7 |
2.6.32-tuxonice and 2.6.32-tuxonice-r1 ... now I use my hdd-based /home |
| 8 |
again and the errors are gone (so far, maybe the re-occur after sending |
| 9 |
this mail, you know ...). |
| 10 |
|
| 11 |
The home-related I/O-errors still happened after poweroff, the "fsck -f" |
| 12 |
showed no errors. |
