--- Comment #1 from Kristof Provost <[email protected]> --- It is of course not a correct fix, but this does appear to make the panic stop: diff --git a/sys/net/route/route_tables.c b/sys/net/route/route_tables.c index 176ca43fa1c5..0000142d0654 100644 --- a/sys/net/route/route_tables.c +++ b/sys/net/route/route_tables.c @@ -345,6 +345,13 @@ rtables_destroy(const void *unused __unused) * and will be completed after vnet teardown. */ NET_EPOCH_DRAIN_CALLBACKS(); + /* + * This drain appears to be unreliable.

I present this more as a possible hint than a suggested solution, though if this gets worse or more frequent we may want to consider applying it as a band-aid anyway. -- You are receiving this mail because: You are the assignee for the bug.
