mptscsih attempting task abort

[Pawel Salek]

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:
         command: Read(10): 28 00 01 0d 0f b1 00 00 80 00

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?
