Hello!
    I have a big problem with my 4.2-stable box. It hangs (all daemon level
activities are shut down, the only working thing is tcp/ip stack and static
 routing - i.e. i cant login from console, all inetd services is dead etc)
 System console is filled with following:
 Dec 17 19:29:55 sentinel /kernel: pcn0: watchdog timeout
 Dec 17 19:29:55 sentinel /kernel: pcn0: watchdog timeout
 (sometimes system does not hang, this log is taken from that cases, in
"hang case" syslogd does not working too)

 Pcn0 is ethernet network card (Allied Telesyn AT-2450F/ST)

Any help on this matter wouild be appreciated. please, as I'm not subscribed
to freebsd mailing list make a cc of reply to [EMAIL PROTECTED]

Kernel configuration is :
