Hi,
My system freezes (crashes) when I run tcpdump on the interface
connected to a 3c905b card. I've tried swapping the card for an other
3c905b card but that did not help. 2 out of 3 times the last message on
the console is "Transmit error, Tx status register 82". sysreq+t doesn't
work. Not only tcpdump, any program which put the interface into
promisques mode makes the system crash. All other interfaces (eth0 and
eth2) are fine. I tried starting the system with 'debug=7' attached to
the modprobe for the module but then the system crashes with a
"vortex_error() status=0x8081".
The tcpdump-problem is reproducable, in fact: the system crashes always
when I run tcpdump on that interface.
This seems to be the only problem with that system: no other crashes or
segfaults or anything out of the ordinary.
