Just a minor heads up: I've merged both Kip Macy's lock order
fixes to the kernel routing code, and the route locking and
reference counting fixes from kern/130652 to stable/7. These
fixes should correct a number of reported network-related hangs.
We might want to release a subset of these as an errata patch to
7.1 if they shake out well in 7-stable.
Unfortunately these changes let my system panic during early boot,
around the time when ppp/routing is started. Backing out these
changes prevents the panic.
I've filed this with some textdumps as: kern/132404: panic sleeping

Hi Ruben--
I've had a number of similar reports, but this one contained enough
information for me to (hopefully) track it down. I've merged a fix
from head as r189531 that corrects lock leak in error-handling in
the routing socket code. Could you let me know if that helps with
the problem?
Yes, Using rev 1.143.2.9 of src/sys/net/rtsock.c indeed solves the
problem, thanks!
