Hi all, <br><br>One of our Dell servers has failed badly, and one of
the domU's has been corrupted in the process. It boots up to a point
and then gives me a kernel panic:<br><br>Loading dm-zero.ko module<br>Loading dm-snapshot.ko module<br>Scanning and configuring dmraid supported devices<br>Scanning logical volumes<br> Reading all physical volumes. This may take a while...<br>
