I took a brief look at your report.  I think a traceback would be helpful.  

echo t > /proc/sysrq-trigger should do the trick.  You're in the middle of
unmount so you might need to go serial console to capture the output.  Your
report metions freeze/thaw.  This is an area where we've had deadlocks in the
past, so I wouldn't be surprised if that is what you're hitting.  We'll have to
see.

Thanks,
	Ben
