I've been experiencing a repeatable panic using ng_eiface(4) on -CURRENT of the last few days. Environment: FreeBSD twiddle.local 5.2-BETA FreeBSD 5.2-BETA #0: Tue Nov 25 19:28:22 UTC 2003 root_at_twiddle.local:/home/data/work/usr/src/sys/TWIDDLE i386 Description: Shutting down an ng_eiface node which has a non-zero lladdr causes a panic.

makeoptions DEBUG=-g', the LOR doesn't show up, but the netgraph panic is still present. The above panic is from -CURRENT as of Tue Nov 25 18:00:00 UTC 2003. This, at least superficially, looks similar to kern/55784 filed against 4.8-STABLE. Find attached a full dmesg, with example script, panic and kernel config. The system is failing to dump core. I'll happily help debug this as much as is necessary before 5.2-REL.
