[X.] Other notes, patches, fixes, workarounds:
I can see two possibly relevant things: classzone & reiserfs.
I'm using reiserfs with no problems since 2.2.14 and reiserfs 3.6.x since
2.3.99-pre9, so I do not think it is reiserfs-related even if it hangs in
umount and I do not use any other fs (well, I'm using procfs, pipefs, shm,
devpts).
I did not tried classzone before.
