Hi all,
after an uptime of 7d10h44m0s I got a panic on my 4.5-RELEASE box (while
4.4-RELEASE was running without a crash for 4 months).
Unfortunately I hadn't a debug-kernel running (which I now have). But maybe
someone has a clue what's going on:
gdb -k kernel.0 vmcore.0:
...
(no debugging symbols found)...

If it occurs again I can give more infos out of the debug kernel.
