Re: kernel panic when running dhclient on tulip

[Adrian Michael Nida <nida@xxxxxxxx>]

Michal,

I just fixed a similar thing for my atheros driver.  You need to add a

lkwt_serialze_enter(ifp->if_serializer);
lkwt_serialze_exit(ifp->if_serializer);

pair to tulip_rx_intr  (which is probably
in /usr/src/sys/dev/netif/tulip/if_tulip.c)

For the atheros code, I was lucky enough to have a NET_GIANT_[UN]LOCK to
swap out.  However, putting the enter after ifp has been defined in the
function and the exit at the end should get you on the right path.

I'm nowhere near a DF box atm and can't supply a patch; but am 99% sure
that is what needs to be done.

Good luck,

Adrian
