Can you double-check this, and perhaps post the dmesg for the 2.6.8.1-mm4
attempt?  It still looks very much like the problem Randy fixed here:

    http://marc.theaimsgroup.com/?l=linux-kernel&m=109313574928853&w=2

I just checked, and Randy's patch is indeed in 2.6.8.1-mm4.  If the oops
still occurs there, it must be a different problem, and the dmesg might
help diagnose it.
