We've had fairly reproducible freezes. After several hours of stress
testing or even overnight not doing anything, everything locks up
including the console.
We then installed a debugging kernel (without INVARIANTS since that
prevented the kernel from compiling at all) and obtained this LOR
when
it froze:
LOR:
1st 0x807d3d90 sleepq chain (sleepq chain) @/usr/src/sys/kern/
subr_sleepqueue.c:773
2nd 0x807c8110 scrlock (scrlock) @/usr/src/sys/dev/syscons/syscons.c:
2526
I have taken photographs of the KDB output following this but have
not
transcribed it until someone says that it will be useful to them. I
could put it up as slightly fuzzy screen photographs on our web site.
The stack trace info would be useful. A photo would be fine.

Sorry for the quality, these were the best I could do with the camera
I had:
http://www.ish.com.au/s/LOR/1.jpg
http://www.ish.com.au/s/LOR/2.jpg
http://www.ish.com.au/s/LOR/3.jpg (this overlaps with [2])
Do you have any hunch about what driver/system might be causing this?
Could it be related to the use of PAE? Because if so, I'd be happy to
leave this server accessible somewhere for FreeBSD developers to work
with and go replace it with a new 64bit system tomorrow for our
production use.
Thanks
