Do you have any core dumps in /var/crash/volatile? If so, I would really like
to get a copy.
I did some digging around in the crash dumps and logs and all (7) panics
had the same stack trace. From the logs:

What struck me was the root: "unix:brand_sys_syscall+211", was this call
from an LX brand zone and if so, was it the cause or a coincidence?
