Subject2.6.13-rc6 Oops with Software RAID, LVM, JFS, NFS
Hi,

I posted an oops a few days ago from 2.6.12.3 [1]. Here are the results
of my tests on 2.6.13-rc6. The kernel oopses, but it the box isn't completely
hosed; I can still log in and move around. It appears that the only things that are
locked are the apps that were doing i/o to the test partition. More detailed info
about my configuration can be found here:

<http://www.icglink.com/debug-2.6.13-rc6.html>

Here is the oops:
