m0n0wall Forum - Device polling in 1.3b branch broken on WRAP

Having a problem with all versions of 1.3b (tried four different versions when they were released and 3x 1.3b9) on a WRAP board. Device polling seems to be completely broken..

Immidiatly when exceeding 10mbit downstream the router reaches its CPU limit and the web-interface is unresponsive.. When reaching 15mbit massive packetlosses (50%) occur.. Cry

On all 1.2 branches device polling works perfectly.. I can reach 20mbps (2.3MB/s), with a max load of 1-2% (with QoS enabled)..

I tried resetting to factory defaults - only setting WAN MAC spoofing and changed LAN IP/MASK - with the same result, so I'm fairly confident that it's not a configuration issue Tongue

Enabling/disabling device polling seems to have no effect at all..

Code:

1.3b9 with polling turned ON (removed irrelevant nics (ath0 / ngx):
$ ifconfig -m

If you need any additional info / tests / configs - let me know..

Update: After some digging, I've tried "ifconfig sis0/sis1 polling", and it completely ignores the cmd, even though ifconfig -m reports the NIC capable of polling.. Doing the same on 1.232 effectively enables/-disables polling..

I suspect it's an issue with the implementation of the sis drivers in this branch/FreeBSD 6.2 build Huh
