Description
ceph version 0.23~rc (a7ed2ee05dc7453942018d7876401c28d3918214)

Linux ss1 2.6.36-020636rc7-generic #201010070908 SMP Thu Oct 7 09:10:00 UTC 2010 x86_64 GNU/Linux
ceph (osd0/mounts) crashes as soon as files are written to the disk.
The setup is at the minimal. one high-end machine with 1xMDS, 1xMON and 1xOSD. using ext4
btrfs shows a similar symptom, in short, any moderate IOs crashes.
It seems to crash as soon as journal parts have been filled up.
When crashed, ceph could be stopped, but mounting can not be redone without rebooting the PC.
CTRL-C is unresponsive.
- start mkbtrfs, start ceph, mount, and dd command.
