Hmm.  I've been running it for a year or two, 24/7, with no real
problems.  I've heard that JFS is not workable on Alpha.  What modern
FSs actually work?

You might look at the strace info in the bug report -- the statfs
syscall returned the correct info, so I think we can rule out the kernel
here.
