I am running 2.6.37 plus the revert of bf9dc102e284 (which is related to drm).
My /home is on btrfs as well as a 1TB external USB hard-disk.
I was compiling 2.6.38-rc3 from /home/mafra/linux2.6 using
the external hd as the destination of the compiled files:
make -j4 O=/mnt/wd/kernel-compile
So after some time I got this bug and I was dropped out of X

Was there anything else before the first bug in dmesg? I would
predict there to have been some additional debugging info, and
probably a USB device disconnect or similar.
If I'm correct, there was an io error while writing to the external
device, which as of 2.6.37 isn't handled terribly well (and errors in
general; in that sense, it's known).
