1. find a big big file 500-600MB or bigger.
2. copy it into a hardware-raid5 mounted device.

Actual Results: Box hangs
The Box is RedHat Linux 7.1 with updates except kernel.
Kernel actually running is 2.4.9-7.4smp found on people.redhat.com. But the
box had the same behaviour with 7.1 older kernels (2.4.2-2, 2.4.3-12..)
The raid controller is an "IBM ServeRAID-4 Ultra160 SCSI controller"
