_rw_wlock_hard: recursing but non-recursive rw radix node head @ /usr/src/sys/net/route.c:831

[Yuriy Tsibizov]

Kip,

this happens on fresh -CURRENT, with configuration similar to one
described in
http://docs.freebsd.org/cgi/mid.cgi?3a142e750812080658r645dc1c4sdd612585
fe9ad7d6 (wpa_supplicant is main suspect in triggering this panic). No
crashdump / backtrace available.

Somehow needlock!=0, and rnh is already locked.

HW is Intel Atom D945GCLF2 (2core + HT enabled) + D-Link Atheros-based
card with WPA and static ip.
