Hello,
my server has started to occassionally misbehave since the kernel
upgrade to kernel-2.6.19-1.2911.fc6.i586.rpm (iirc). It has 4 SCSI
disks in total, 3 of them are running in a software RAID5
configuration. The kernel produces now and then following messages:
mptscsih: ioc0: attempting task abort! (sc=d674b200)
sd 0:0:3:0:

mptbase: ioc0: IOCStatus(0x0048): SCSI Task Terminated
and so on. These errors appear to be triggered by a disk activity, eg.
rsync process. Now, I am not 100% positive it is purely software
problem but when I downgraded to older kernel releases, the errors
appeared to be gone. Since the errors are not entirely predictable, I
cannot be sure.
Has anybody else seen something similar? What kind of information would
be needed to debug it properly and establish the underlying cause of
this problem?
