I had a severe filesystem corruption.
Later, I've played a bit with my laptop's HD to find the reason for it.
when disc enteres stand-by mode and when woken up, driver says:
hda: write_intr: Status=0x50 { DriveReady SeekComplete }
after that ( sometimes ) it appears completly inaccessible:
hda irq timeout: status=0xd0 { Busy }
Such an error results a mess of files on a rw mounted filesystem.
If / is mounted rw from same disc, the only way to feel safe is to
hold a backup tape in a hand.
The easy trouble-maker is "hdparm -Y /dev/hda", but HD timeout in BIOS
Setup makes the same.
If you can explain me what's up, it will make me feel better.
Can you supply any hints, what could it be?
Thanks.
P.S. I'm not in the mailing list. Please, reply to kirill@qdn.miee.ru
