A few other solutions I had with reiser
Was seeing consistent sleepycat database corruption together with the type of log messages you described on MD softraids about 6 months ago
I ended up dumping the reiser for xfs and upgrading the kernel from 2.6.8 to 2.6.12
For reasons of performance/stability/realiability, some of these systems needed 3ware raid controllers which required kernel upgrades to 2.6.16
I would have liked to have stayed with reiser, but it just didn't seem to behave well in the Debian amd64 OS
Today I have over 100 happy Debian amd64 servers running 2.6.12/16 with xfs on soft and hard raid configurations

Meh. I stopped using my desktop for real work a while back, since it
locks up under load. If I ask nicely, they take my machine away for a
week, sit on it, then give it back to me.
