HP Proliant DL380 G3 1x 2.8GHz Pentium 4 Xeon HP CCISS BIOS v2.58 Version-Release number of selected component (if applicable): xen-3.0-0.20051109.fc5.3 kernel-xen-hypervisor-2.6.12-1.13_FC5 How reproducible: Always Steps to Reproduce: Install xen, kernel-xen-hypervisor-2.6.12-1.13_FC5, reboot, wail, gnash teeth. I also tried building the ciss driver into the kernel, with the same lack of results.

Doh, my bad. As part of the debugging that I was doing to 2.6.12-FC4-1456, I tried disasbling IOAPIC mode on the xen command line. This didn't fix the problem, I then rebuilt the -devel FC5 kernel, and installed this, and the kernel package carried the debug noapic setting over. With this turned off, it now works... I will try and find out which kernel fixed it, and draft some changes for the Fedora/Xen quickstart wiki. Sorry for the bother...
To clarify, if I ommit the "noapic" xen boot time paramter, the xen-3.0-0.20051109.fc5.3 + kernel-xen-hypervisor-2.6.12-1.13_FC5 combo now seems to work...
