Looking through the archives I can not find any resolution to the problem. The specs on my machine are Dell Poweredge 1850 Dual Xeon 2.8s 1gig ram PERC 4e/SI raid controller in mirror configuration with 2 73 gb drives (uses the megaraid_mm/megaraid_mbox modules) Any time the system is placed under high IO ( for example untar/bz2ing a tarball to create the fs for a xenU partiton) the machine hangs. There are no kernel messages. The console becomes completely unresponsive (pressing Caps lock does not change the status of the caps lock light) I can't use the magic sysreq key. I've tried adding "watchdog" to the end of the grub line that loads xen.gz. That didn't change anything. I've also tried disabling hyperthreading with no success. I'm using xen 2.0.5 with a 2.6.10 xen0 kernel. My raid controller bios is already at version 516a (the newest I can find on the dell site.) Does anyone have any more suggestions for me. Thanks, -Rob
