I am experiencing the same issue with random reboots after a 5.3
upgrade. Sometimes it will go for days without rebooting then today
it has rebooted 6 times at random times. I have modified grub.conf to
go back to 2.6.18-92.1.22.el5xen on my dom0 and my only domU so we
will see what happens (or hopefully doesn't happen) the next few days.
I have a 3.0 P4 CPU with HT that does not support 64-bit so it's
running an i686 kernel. It does have a Broadcom NIC like an earlier
post was suspicious of:
02:08.0 Ethernet controller: Intel Corporation 82562EZ 10/100 Ethernet
Controller (rev 02)
02:09.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5703X
Gigabit Ethernet (rev 02)
I have upgraded about 8 other servers with no random reboot problems
but they are all running on a newer processors with a 64-bit kernel.
