Hello Robert.
Today i install new freebsd box with freebsd 5-stable, sources from are
over Jun 6 09:28 EEST.
when i tried to work I got are full repeatable panic.

other panic with 'Panic String: sbdrop', but for it i can`t have
backtrace.
Repeat it trivial - at this host i have are ircd daemon who restarted
via cron script. I tried to connect to ircd port (via loopback) at near
start time and got a panic.
If you need additional info ask me directly - i`m not are subscribed to
list.
