re[3]: Troubleshooting?

[Greg Freemyer <freemyer@NorcrossGroup.com>]

This is not looking like an XFS issue.

I downloaded the kdb patch and installed it.  My kernel source tree is on an ext3 drive.

I've had 2 lockups in the process of trying to compile the new kernel. :(

I'll switch to a different kernel, get kdb compiled in and see what it shows shortly.
