System hang with RedHat 5.2 and AHA 2940UW

[Bernd Kossmann]

Hello

after installing RedHat 5.2 on an new Pentium II (Asus P2L97 Board)
system with Adaptec 2940 UW controller and IBM DDRS-34560 disks
I 've got the following intermittent error:

aborting command due to timeout : pid (17324), scsi0,channel0,id0,lun0
write (6) 01 00 34 02 00
scsi host 0 abort timedout - resetting
scsi bus is beeing reset for host 0 channel 0

Just doing an "ls  -lR" and the system hang for 10 - 20 seconds with the
above
error message. During installation the same thing happend.

The contoller termination is automatic and only the internal cabel is
terminated,
no device . Reducing the transfer speed to 10 MB/s doesn't change anything.

Thanks for any tips and help
