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.
--- A P4 with HT...? This may not be your problem but I have several P4 CPUs with HT Enabled. Do you get messages in /var/log/messages/ about your cpu temp is above thresh hold and that will throttle back cpu 0 or 1 constanlty? Also just currious are you using "p4-clockmod" driver? On a reboot that had happened those were the messages I had in my logs.
