Fedora 11/12 kernels as xen domU

[Norman Gaywood]

Is anyone having any stability with the fedora kernels running as a Xen
DomU. Dom0 is a Centos 5.4 2.6.18-164.9.1.el5xen kernel.

These fedora kernels seem to lockup (processes get stuck in D state)
whenever put under any load:

kernel-2.6.30.10-105.fc11.x86_64
kernel-2.6.31.6-166.fc12.x86_64
kernel-2.6.31.9-174.fc12.x86_64

Yes, I tried a fedora 11 kernel on a fedora 12 system. This is the most
stable for me.

Here are some bugzilla entries (one posted by me) that point to this
problem:

kernel 2.6.31 processes lock up in D state

FC12 2.6.31.9-174.fc12.x86_64 hangs under heavy disk I/O
