Hi,
After testing 2.6.29-rc1 on xen-x86 with a btrfs root filesystem, I
got the OOPS quoted below and a hard freeze shortly after boot
(running update-grub of all things).
Boot messages and config are attached.
This is on a test system, so I'd be happy to test any patches.

Are you able to reproduce this without using btrfs?

Hi,
Sorry, it looks like this message made it through after all - I had
resent it with inline config/etc after it appeared to vanish into a
spam filter somewhere, and discussion is happening in that thread
instead: http://thread.gmane.org/gmane.linux.kernel/779350
(message-id <[email protected]>)
It's been bisected there, and I believe there's a revert queued
already as a short-term fix.
Thanks,
Bryan Donlan
