I have checked my logs. I was not able to find anything from reiserfs. 
But I have uploaded my syslog since feb 27 (this is when the bug occured):

http://nuk.teteny.elte.hu/~selli/syslog.1.bz2 ( 1.8 compressed, 300M 
uncompresed )

It may has more information about the bug, you should check it.  For 
example the very first message from reiser4 is:

Feb 27 12:59:38 sunset kernel: WARNING: Wrong level found in node: 1 != 95
Feb 27 12:59:38 sunset kernel: reiser4[cupsd(3296)]: parse_node40 
(fs/reiser4/plugin/node/node40.c:767)[nikita-494]:

My machine (seems to be) is fun, I have run some tests.
Another info:
I was using an extrenal usb2 disk (120Gb/ reiser4) when this affair 
occurd. After rebooting I had to repair all my reiser4 partitions. ( / 
hda2,   /home hda5/,   /mnt/Movies sda1).

For the "/" I had to use --build-sb, then --build-fs, then --fix
For /home, and the external /mnt/Movies just the --build-sb

have no crash since I replaced it)
