I just reproduced this with a 2.6.38 kernel. Previously I was testing a 2.6.39
kernel. I have NOT tried this with factory, nor with a 3.0 kernel.

This time I was just confirming the oops would still trigger with a older
version of the xfstest we are working on. The current version no longer
triggers a oops.

====
I was working the xfstests git tree cloned via:

git clone https://github.com/adityadani/xfstests

# Then, get an older commit that apparently has a userspace bug that triggers a
kernel oops.

git checkout 1b712a4512d63502fab6

# Then prep for the test

export TEST_DEV=/dev/sda3
export TEST_DIR=/xfstests_mnt
export SCRATCH_DEV=/dev/sda1
export SCRATCH_MNT=/xfstests_mnt_scratch
export FSTYP=btrfs

umount $TEST_DIR
umount $SCRATCH_MNT

mkfs.btrfs $TEST_DEV
mkfs.btrfs $SCRATCH_DEV

mount $TEST_DEV $TEST_DIR
mount $SCRATCH_DEV $SCRATCH_MNT

# Then run the test

/check 255

I didn't keep the oops, but it seems reproducible enough.

The oops was also put into the kde-oops catcher.
