Some additional info after reading 208333 once again: - Decreasing the transfer speed does not help - Nor does adding the mptscsih="width:0 factor:0x0A" option to the kernel. # cat /proc/mpt/version mptlinux-3.04.03 Fusion MPT base driver Fusion MPT SPI host driver [root@hemulen]# cat /proc/mpt/summary ioc0: LSI53C1030, FwRev=01032700h, Ports=1, MaxQ=222, IRQ=11 ioc1: LSI53C1030, FwRev=01032700h, Ports=1, MaxQ=222, IRQ=10 Can you please try with the latest kernel-xen from updates-testing? There is a fix in that which addresses an interrupt-handling bug which could easily result in what you're seeing. Writing this answer running the new kernel. So its at least better than the old one. Coming back when I've tried a little more. BTW, is there a GPG key for updates-testing? If so, where? --alec Now I've tested a little more, and I shouldn't have been so lucky a few minutes ago ;-) No, the kernel is not stable. The first time I tested (and wrote previous message) I was able to start a windows hvm guest ok. However, after a few minutes the system locked up completely, totally dead and I had to reboot. I have now restored the SCSI transfer speed to 320 Mbps. After doing the this, the new kernel locked down more or less immediately after logging in. This time it's not possible to start any text console - it's just dead. Sorry not beeing able to provide anyh mer more precise info...' --alec Using the new kernel, do you get anything that looks like a stack trace or Oops message on the console? If it is not being written to logs, a picture of the screen would be useful. There was absolutely nothing on the screen, it just frooze. I'll attach /var/log/messages Created attachment 156196 [details]
Excerpts from /var/log/messages
Excerpts while booting released kernel 2.6.20-1.2952-xen.fc6. Ends with a
power-cycle reboot.

Working grub.conf
Resolved! Adding NOAPIC boot option to the xen kernel removes problem.
Notes: Not sure if bug should just be closed, or somehow sent to the
installation program. The root cause in my case was the grub.conf generated by
the kernel installation rpm which didn't copy the noapic option present in the
normal kernel boot line to the xen kernel boot line. Leaving bug open.
But of course, the real root cause is my limited brain.
