What file system were you using before ReiserFS? I'm no expert but it seems, based on what you said about the raid resyncing just fine while a filesystem call blocked, you may want to look at the filesystem you're using. RAID provides a block level interface to the FS and if the block level interface is working and not reporting errors from lower levels, your culprit is higher up the chain, ie the FS. It's perhaps a matter of personal preference but I try to avoid Reiser. It's not that it's a bad FS or anything but I've never had it work quite right for me. Plus, based on my read of how it works, it requires more processing on file creation due to the various optimization algorithms it uses. -- Drew "Nothing in life is to be feared.
