Also, the following message appears in the system log: vr0: watchdog timeout If the network stays down for longer than 10 secs or so, multiple copies of the above message appear in the system log (I got up to 20+ once). Also, I have also seen the "rx error: unknown rx error" message in syslog (see kern/17866), but that is much less frequent than the "watchdog timeout" message. >How-To-Repeat: Any sort of moderate to heavy traffic load (Samba, FTP, etc) can cause the card to lock up for a relatively short period of time (10-20 secs). >Fix: Get to a pre-MII-bus version by doing the following: Back out /src/sys/pci/if_vr.c to version 1.17 Back out /src/sys/pci/if_vrreg.h to version 1.6 Recompile kernel. Reboot (there might be syslog messages about miibus conflicts.. haven't tried to track them down yet, they're probably due to not removing mii bus from my kernel config). >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
