  Hi Andrew,

  Thanks for the tip. I booted with nmi_watchdog=0 and was able to get a full 
sysrq-t as well as a sysrq-m. Since it might be a little too big for the 
list, I've put it on a text file at:

 http://193.136.132.235/dl145/dump1-2.6.12-rc2.txt

 I also made a run with the mempool-can-fail patch from Nick Piggin. With this 
I got some nice memory allocation errors from the md threads when the trouble 
started. The dump (with sysrq-t and sysrq-m included) is at:

 http://193.136.132.235/dl145/dump2-2.6.12-rc2-nick1.txt

 Let me know if you find it more convenient to send the dumps by mail or 
something. Hope this helps.

 Thanks,

Claudio
