Hello,
A message was already posted here regarding this issue-
I experience the same problem with 6 machines, all with Hitachi
harddrive, VIA Motherboard which uses the sata_via driver:
Once every few days each machine freezes or just stops reading from the
HD and throws i/o error messages as pasted below.
Note that the first "ata exception Emask" errors apear right after
booting, when harddisks plays smoothly. the I/O errors apear only after
few hours-days.
Is it a known problem? (Already two posts regarding this)? Any solution
or at least a way to check it?
(I'm using CentOS5 with the latest updates)
