Kernel Panic - interrupt / if_re related?

From: Shawn <adonijah@xxxxxxxxx>

I'm using a custom configured kernel (although I haven't done anything but
comment out drivers I don't use) with the if_re network driver
(which Joerg recently updated). Since I started using the if_re driver
again I've noticed a storm of livelock messages in the console, and twice
tonight I've had a kernel panic while in X (thankfully I have DBB
UNATTENDED enabled). I've been updating my kernel and doing a buildworld,
installworld, and kernel every day now for a while. My kernel is current
as of the tcp_output.c commit Matthew Dillon made August 2nd.

I'm using gcc2, and both panics have happened while doing a make world on
one of the virtual consoles while in X.

I've provided links to a backtrace, a full backtrace, pciconf -l -v
output, vmstat -i output, and my config below:

(my config for "debug trim")

As you can see from the vmstat -i output, interrupt 11 for the re0
interface generates an incredible amount of total interrupts (22047896 in
39 minutes of uptime).

I'll keep the vmcore for a few more days, but I'd rather not have to
upload it anywhere on this cable connection (1gb, a few hundred mb
compressed I imagine)...
