Yesterday evening I fetched the lastest from svn stable (r354662),
created a custom kernel configuration with the following options, and
rebuilt everything;
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
include GENERIC
ident MACBOOK
# For full debugger support use (turn off in stable branch):
options BUF_TRACKING # Track buffer history
options DDB # Support DDB.
options FULL_BUF_TRACKING # Track more buffer history
options GDB # Support remote GDB.
options DEADLKRES # Enable the deadlock resolver
options INVARIANTS # Enable calls of extra sanity
checking
options INVARIANT_SUPPORT # Extra sanity checks of
internal structures, required by INVARIANTS
options WITNESS # Enable checks to detect
deadlocks and cycles
options WITNESS_SKIPSPIN # Don't run witness on spinlocks
for speed
options MALLOC_DEBUG_MAXZONES=8 # Separate malloc(9) zones
options VERBOSE_SYSINIT=0 # Support debug.verbose_sysinit,
off by default
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Then this evening, another system hang, no debugger messages or any
sort of output whatsoever! :-( The only upside is that I'm experiencing
these hangs almost daily now, so going to try a process of elimination.
The hangs generally seem to occur when I'm working using Sublime Text 3
(via the linuxulator), with an open xterm window or two with X11
(currently using the Intel video driver). So might try switching to
modesetting video driver, or using an editor that is native, or ditch
the graphical environment altogether and see if I still get issues
working on the console.
If anyone has any ideas on how else I may be able to track down the
issue, please let me know! :-)
Thanks,
James

Can anyone offer some advice as to how I can track down this issue?
The first question which I couldn't see from your dmesg is "do you
have ht krnel debugger configured into your kernel?"
Nope it isn't, I will build it in, is it just adding options KDB and
DDB?
Another problem I have is I don't seemt to get any crash dumps even
though I have 'dumpdev="AUTO"' in my /etc/rc.conf, could this be due
to my system using a swap file (md) rather than a dedicated swap
partition?
