Hi, I got a crash when I shutdown a XEN PV guest.
This Funtoo guest is freshly installed and the bug is easy to reproduce.
* I have lot of Reiser4 partition on bare metal with the same
kernel, no problem
* After 3-4 times crashing it, running fsck return no corruption.
to reproduce :
- create a Xen PV with a Reiser4 /
- issue the command : poweroff
tanith xen # xl create -c metro.pv
Parsing config from metro.pv

To: Edward Shishkin; +Cc: reiserfs-devel
3.15.0-rc3-Miner-dirty is the rc3 from git + the reiser4 patch
I retested the VM and with kernel 3.12, 3.13 and 3.14, it's fine.
The problem is only with 3.15-rc3 and now rc5 that I just compiled.
Still, it affect only the VM with a Reiser4 (reg40) /. Don't have any
problem with the host but the / is not reiser4. The host only have a
luks Reiser4 partition (ccreg40) on a second HDD.
The patch apply but something probably need to be changed.
