kind of strange getting a new release with a known not functional driver

This is not quite true; I am running 2 systems with the sk driver. One of
them is a dual core athlon64, and it's network connection is indeed flawed
unless I change debug.mpsafenet to 0. The other machine is a regular
athlon64 and has no problems at all. Both systems are running
6.1-PRERELEASE amd64.

With debug.mpsafenet=1, cvsup failes with "protocol error"s on the SMP box.
Also, I run several Half-Life: Counter-Strike servers on it and clients
occasionaly receive corrupted UDP packets which cause them to drop the
connection. However as soon as I changed debug.mpsafenet to 0, all problems
were gone.

So, maybe you should try changing debug.mpsafenet.
FYI: the SMP box has an Asus A8V (agp) mobo, and the other box an Asus K8V
SE.


probably you do not have the traffic to make the box crash or less then 1/2GB
of RAM in use

in fact the problem does not happen on UP machines, only some times a device
timeout which only ocasionally cause rx/tx to stop

The problem is appearing on SMP machines

when you have less then 2Gb of RAM the problem ocurres once a day or so and
seems to depend on memory use and amount of traffic

soon the traffic reaches more than 1Mbit/s the crash is predictable and you
can wait to see

on 4GB of Ram machines and more traffic the crash is imediatly and worse when
the box crashed under load (4-6Mbit/s) and comes back then the high demand
strokes it and it crashes in minutes or imediatly soon the network is up

so probably mpsafenet may help by not processing concurrent packets but this
is a workaround not a solution (for me)

last time I checked mpsafenet=0 almost cut 1Mbit/s of traffic and the overall
performance/response was bad, higher HZ did not resolved anything and
disabling polling made it still worse (I have other NICs installed), the
machines are working as GW

until january the machines didn't crashed, only timeouts and rx/tx stops
I used Pyun's driver and the timeouts went away, thank's again!

so then I got confused by some if_sk talks on stable and thought the driver
was comitted and the boxes started crashing until I got it last week and
reused Pyun's driver again and my sk problems are gone again, the machines
are stable for 4/5 days now
