Bad luck, my box is still not stable even though this bug has been fixed.

I'm working on it.  There are several issues that will take me a couple
of days to work them out.  My two main projects are

 - rebuilding RedHat 4.9.1 for big endian MIPS (like the Indy).  This is
   the most urgent part and I'm working (well, my Indy ...) on it.
 - my kernel tree has diverged significantly from what were publishing
   on Linus.  Have to merge them both.

You can usually get the bugfixes from the kernel sources/binaries available
on Linus.  The last one is a bit old, though ...
