I'm not sure it is ipfw related, as i can't stop ipfw for test (it's production machine). i just added workaround now to reset bce1 every 10 minutes. >How-To-Repeat: use bce interfaces with FreeBSD 8 and ipfw. I am not 100% sure if it's related to bce1 but i have such problem only on THAT server which was running fine with FreeBSD 7 (but slower, ahci driver from 8.* is really worth of update) >Fix: no idea what it is. adapter is actually working, it's some kind of routing/ipfw problem. please reply to e-mail if you need detailed configuration. >Release-Note: >Audit-Trail: >Unformatted:
