Hi,

I sanboot installed redhat 5u7 x86_64 os on UCS, and then mapped 15 volumes to run IO,  os will become kernel panic less then 2 hours.

then I have to force power cycle the server.

The card used is M81KR.

Hello

You can get the driver version by executing following command in RHEL

modinfo enic

modinfo fnic

Can you consistently reproduce the crash ?

I am not aware of any known issues.

Please open a TAC service request with above information and also upload Redhat logs ( which can be collected by executing "  sosreport -k rpm.rpmva=off " command )
