Thanks for the pointer - which I knew about, but unfortunately found out
too late that the kernel needs to be compiled with options STACK and/or
options DDB/KDB for this to work.
Could this information be added to that page?
I already recompiled the kernel, but are ambivalent about whether I
should now hope to see the deadlock again... ;-)
One more thing: Could you point me to the SVN revision in head and/or
stable/9 which presumably contains the (partial) fix?
