Often I can only run the -rc kernel for a few hours on the box that currently shows the problem, and that's not enough to hit the fault. I've configured a XFS partition on my home workstation and I'm keeping that one busy doing various rsync's and running benchmarks etc - putting as much different stress on the XFS filesystem as I can. I'm also setting up a test box at work to try and duplicate the problem on a non-production server. I won't be able to duplicate the setup exactly, but it'll be close. > > > > See the thread titled "2.6.18-rc3-git3 - XFS - BUG: unable to handle > > > > kernel NULL pointer dereference at virtual address 00000078" for the > > > > full story. > > That, and another story - Jesper hijacked that thread ;) - the Sorry ;) > inital bug there was found and fixed, and the fix has now been > merged.
