After theese 30s, the box is allright and everything works fine again. In /var/log/messages, this message : "Sep 14 01:32:49 gaia kernel: (ips0) Resetting controller." Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. find a big big file 500-600MB or bigger. 2. copy it into a hardware-raid5 mounted device. 3. Wait for the hang or the end of the copy. 3. find bigger file if necessary Actual Results: Box hangs Additional info: 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"
