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.
