Thats routes are using ISA and PCI PCCARD adapter. Our problems are happening with some routers, using 4.5-RELEASE-p4, 4.5-RELEASE and 4.3-RELSEASE. It's happening after 1 or 2 hours working fine when all traffic stops and it's logged like this: /kernel: wi0: xmit failed /kernel: wi0: watchdog timeout /kernel: wi0: init failed /kernel: wi0: failed to allocate 1594 bytes on NIC /kernel: wi0: tx buffer allocation failed /kernel: wi0: failed to allocate 1594 bytes on NIC /kernel: wi0: mgmt. buffer allocation failed /kernel: wi0: timeout in wi_seek to 0/0; last status 4000 /kernel: wi0: timeout in wi_seek to 0/44; last status 4044 When it happen only after a reboot cycle (without power cylce) all returns to work fine. There is a very important fact: when we remove the card from its adapter and after a little time we reintroduce again (there is one power cylce here) it can't work, only will work after a reboot, without a power cycle. We think could be some situation which the wi driver can't answer correctly. In this router we are using a NIC manufatured by "Avaya Communication" but this problem is happening with other releases and Lucent cards. There is a strange fact: during whole weekend none of routers lost its connection when our traffic is low. >How-To-Repeat: About 10 machines connected by only one WavePoint II with OR (out door router) license. The WPII is conected by ethernet port with a AP1000 which connect this bridge to main site. The WPII are configurated to work like a bridge and there is a amplifier before an omini anthena (15db). We are using WEP encriptation and there is wireless card inserted in B slot to send signal to other site by parabolic anthena which work final all time. When all trafic is very high some cards are freezing and they lost connection with WPII. When it's happening that router become very slow during 3 minutes, like a frozen CPU interrupt, after that it returns to work fast for 5 seconds and this cycle repeat until someone press <ctrl+alt+del>. That problem happen with 4 routers and always happen with same routers. Other 6 routers are always working fine. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
