I have been using linuxcnc 2.9.0~Pre0 from sources, run in place.
Until today, it has worked, mostly. Before today, about 2x per week
it would freeze and I had to cycle power to get it working. Now,
linuxcnc freezes.
Does it ONLY freeze when LinuxCNC is running? But, just keep working
if you DON'T start LinuxCNC?
In that case, the most likely problem is the BASE_THREAD has too
short a period. Try increasing
the BASE_THREAD period in the .ini file and see if that fixes it.
I changed the BASE_THREAD period by a factor of 10x then 100x, with
the same result.
The OS seems to run fine. I did:

All this went OK. Elapsed time 20 min, or so.
OK, so ONLY your GUI is freezing? One other thing is if you load a very
long and complex toolpath, then the
3D preview window can lock up for a long time.

Perfect example of poor design where the OS with RT kernel is configured
with all the software needed for GUI and multimedia!
It took me 20 minutes to install linuxcnc-2.7-wheezy.iso in virtual
machine. It's not the same as on bare metal of course but most things
should work under such circumstances.
Linux linuxcnc 3.4-9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55-4linuxcnc
i686 GNU/Linux
rs@linuxcnc:~$ lsmod | wc -l

one a set of modules is sound related
snd_intel8x0
snd_ac97_codec,snd_intel8x0,snd_timer,snd_pcm,snd_seq,snd_seq_device
Default installation has sound modules active on CNC?
LinuxCNC program started fine. I was able to power it on.
When I started milling test axis.ngc it failed due to RT error. Not a
surprise for a VM. I was watching a TV program on my workstation
connected to Silicon Dust box over the network at the same time as VM
was running. As soon as I turned the TV app VLC off I was able to start
virtual CNC milling. Amazing how many things can be done on one system.
I poked around CNC kern.log and other logs. It's easy to see that there
is a lot of useful information for troubleshooting.
