Same here. It was really bad with a version from about a week ago, but
after updating on the 19th, so I got the changes from ozaki-r@ related
to multiprocessor safety, it got much better. Still happens, though, on
the system I'm attaching dmesg.boot for.
The hang is hard enough that hitting the NMI switch doesn't do anything,
which is interesting.
And while on that topic: the current handling of NMI on the amd64
multiprocessor platform seems not quite right: we get output from each
processor saying that it's responding to the interrupt, and continuing
afterwards doesn't work, either. I've played with it a bit, and have
something that at least lets just one CPU actually handle the NMI, and
where continuing works right. A new NMI after resuming doesn't have any
effect, though, so I guess the non-maskable interrupt is. :)
If someone who knows how this stuff actually works would like to look at
the code, and what I've done with it, I'm attaching my current diff.
I won't be surprised if I'm doing this all wrong...
