Random server reboot after update to CentOS 5.3

Fri May 22 08:14:39 CDT 2009

Sounds scary,

Have you tried installing the broadcom drivers + firmware from dell's support site or is it a pure centos kernel ?

BTW : I can confirm no panics with heavy NFS loads on CentOS 5.2 :

System : PE 1950 III 4Gb RAM
NIC : Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (from lspci)
Kernel : 2.6.18-92.el5 #1 SMP x86_64
Bnx2 driver : bnx2 v1.6.9 (December 8, 2007) (from centos)
MTU : 1500 on eth0 and 9000 on eth1 

No issues at all mounting a lot of heavy traffic maildirs over NFS from a Netapp for nearly two months. Same holds true for a MySQL DB on a Netapp over iSCSI.

Cheers,

Robert
