Description Levente Farkas 2007-07-04 10:31:45 UTC

Description of problem:
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
arise 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.

Comment 1 Peter Martuccelli 2007-08-10 17:50:21 UTC

This is fixed in the SATA update shipping in RHEL 5.1.

Comment 2 Levente Farkas 2007-08-11 13:30:13 UTC

when will be released?
anyway we alredy replace the sata card since even after a month there was not
even a comment on this bug:-( at least a "we're working on it" would be useful...
