Whatever changes made it into 7.1-RELEASE appear to have mostly fixed
the problem. With 7.1 the system runs fine except for the problem
described below.
After about 7 hours of uptime the system fails due to an interrupt storm
between what looks like the nVidia controller, network interface, and
USB controller. Changing the em0 interface status to down stops the
interrupt storm however it returns as soon as the interface is enabled
again.
Let me know if you need more data.
Thanks,

dmesg log:
============
16:02:44 -- Starts generating interrupt errors:
"interrupt storm detected on "irq21:"; throttling interrupt source"
16:02:45 -- em0: watchdog timeout -- resetting
16:02:45 -- interrupt storm detected....
16:02:45 -- em0: link state changed to DOWN
(...)
16:02:49 -- em0: link state changed to UP
The above repeats regularly but is partially squelched by "last message
repeated x times" messages.
