Aborting Command

[Dariush Shirazi]

Hello,

I have a 2 processor PPro 300 (HP Kayak XU) which has been locking up 
during backup every other night. For a while, I thought it might be the 
SMP. So I removed the SMP flag, rebuild and reinstalled the kernel. It 
crashed again last night.

This is the error I get (retyped):

	scsi: aborting command due to timeout 
	pid 813970
	scsi 0 channel 0 id 0 lun 0
	write (10) 00 00 43 df ...
	read (10) 00 00 43 df 00 00 04 00

I have tested the disk using the controller VERIFY pass and no bad block
was reported. 

Thanks a lot for any information/hints. Also, since I am crashing every 
other night, I can try different things and wait 48 hours (works like a 
clock).

System info:

	2 proc Pentium II 300
	2 scsi cards (on the mother board)
	1 disk (Seagate ST34501W)
	1 tape (HP C1537A DDS3 dat)
