alt+sysrq+p does wierd stuff (is that new patch in your tree Andrew?
doesn't seem to inter-react with the other NMI code well)
What patch?
Sorry.
nmi-lockup-and-altsysrq-p-dumping-calltraces-on-_all_-cpus.patch
It does seem to work. But probably needs some cleanup for the NMI
errors.
If you give me to know where the problem come from I can fix it and make a cleanup.
It gets a lot of the "dazed and confused" errors. Possibly you just need
to disable that part of the handler?
can you try this cleanup patch?
This fixes the problem for me, though I do no like the way it does so
very much...
