Intel 024B server deadlock

[Rashid N. Achilov]

Intel server (configuration below) with 4 SCSI and one IDE drives. When I try 
to READ big archive file (i.e. 150-180 Mb) idependently, through tar -xf 
filename.tar or reading through Samba, from IDE drive (ad0) box throws a 
message

Jul 30 16:11:38 svr-63 kernel: ad0: TIMEOUT - READ_DMA retrying (1 retry left) 
LBA=151318527

and goes to deadlock after 5-10 sec. No any response even for keyboard 
pressing, mouse movement ,etc. - only reset. Where is a "problem root" here? 
In physical drive? In server? I hadn't have work with Intel servers before.
