Hi. Recently I switched to WITH_NEW_XORG, primarily because the stock X server

The new X server and Intel driver works extremely well, so kudos to whoever made
this possible.
Unfortunately, I am now experiencing random hangs on shutdown. On shutdown the
system randomly freezes after
[...] syslogd: exiting on signal 15
I would then expect to see 'Waiting (max 60 seconds) for system process 'XXX' to
stop messages, but these never arrive.
I paniced the machine in ddb, so I have a crash dump if someone want to look at
it. The crashinfo is at http://barrytown.boland.org/core.txt (I would have
pasted it here but it is a bit verbose.)
Machine has an Intel G41 chipset, with a SAMSUNG SSD 830 Series HD, running
9.1-STABLE r251803. Serial console. GENERIC kernel, expect for options DDB and
ALT_BREAK_TO_DEBUGGER.
Who knows what's going on here?
I do not see anything related to i915 in the core.txt you provided.
Next time the machine hangs, start with the output of ps command from
ddb and 'show allpcpu', together with 'alltrace'.
Ok.
I appended 'thread apply all bt' from kgdb to the core.txt, maybe there is
something interesting in there.
I did notice the following

Previous frame inner to this frame (corrupt stack?)
Maybe the hang is caused by the removal of the text mouse cursor? (Just guessing
here.)
Cheers
