hi,
we've got a server with 6 sata disk (2 system raid1, 4 data raid5).
recently we've got such error is the log and in these case the system is
totally hang ie. it seems to crash but after 30-40 sec is start to
working. we already 2 times replace the sata cables the problem still
arrise what's more with different data disk (so not the same). we assume
it can be some kind of sata driver bug or motherboard issue?
kernel-2.6.18-8.1.6.el5.x86_64 on gigabyte ga-81955x motherboard with
SAMSUNG SP2504C disks.
anybody has any tipp?
thanks in advance.
