This is my first and only reiser4 filesystem, and has not been used
with any other kernels.

fsck.reiser4 didn't seem to find anything, and the problem reoccured
after reboot

I had the same problem with this kernel, ent:hda5 was using all cpu time.
2.6.12 with latest patch for it works the best for me.

Sorry to say that latest big changes made reiser4 into a bit of a
turkey.  vs, can we warn about this somewhere?

There is a warning in reiser4 changlog on namesys.com ftp, it's about 2.6.13-mm1 if I can remember but I guess it points to the same code. Maybe Andrew Morton can put the same warnning in his changlogs for -mm.
