[gentoo-user] Oops when mounting (some) XFS volumes

[Eric Martin]

I'm at the end of my rope with this problem and I'm hoping that people
here can help.  I have a few boxes that are Oops'ing on startup due to
mounting some xfs volumes.  I created a machine with the 2008.0 live
cd and the stage3-i686-hardened tarball.  I'm using xfs on top of lvm2
and some xfs volumes will mount while others won't.  I first noticed
this in 2.6.27-hardened-r3, but I've since compiled

2.6.24-gentoo-r8 (same kernel as livecd)
2.6.27-gentoo-r7
2.6.27.10 (vanilla)

and they all have the same problem.  home, tmp, usr, and var are all
xfs volumes (on top of lvm) but only var refuses to mount.  I'm using
the same kernel config (albeit churned through make oldconfig) to
eliminate and discrepancies but I don't think it's kernel related as
they all do it (or I'm configuring the kernel incorrectly).  Here's a
quick summary of the relevant livecd utils and what I currently have
on my box:


livecd
xfs 2.9.7
lvm libary 2.02.28
lvm library version 1.02.22
lvm driver version 4.12.0

my box
xfs 2.10.1
lvm libary 2.02.36
lvm library version 1.02.24
lvm driver version 4.12.0

I've looked through b.g.o, gmane and google but I couldn't find
anything relevant.  I'm attaching a trimmed version of dmesg with the
errors and my emerge --info.

Thanks!
BTW, I just used a different fs on another machine with this problem
but either something is broken and should be fixed, or I'm doing
something incorrectly and need to be educated.
