I sent this message to sparc@ and received no reply, except strangely enough from a buddy at Sun. Can anybody give me some guidance on making sure I get panic information and/or a DDB prompt?

Begin forwarded message:
Just a heads up, since I can't really provide much more information than the dmesg output below, but I am consistenly able to lock up my V100 *hard* just by scp'ing stuff from it.

The first time I experienced the problem, I plugged a serial console in and had a DDB prompt, but ever since with something watching the console full-time, I've just gotten a locked-up machine and no DDB prompt or panic information. Any tips for making sure I'm able to get either one?

Any help is sincerely appreciated.
