I have seen watchdogs much earlier then FASTINTR.

We've a lot of computers w/FASTINTR (more or less patched). They carry huge traffic. But I don't remember when I have seen last watchdog. E.g.: pitman:~# sysctl dev.em.0.stats=1; dmesg | tail -30 dev.em.0.stats: -1 -> -1 [skip] em0: Excessive collisions = 0 em0: Sequence errors = 0 em0: Defer count = 0 em0: Missed Packets = 44614035 em0: Receive No Buffers = 5082415 em0: Receive Length Errors = 0 em0: Receive errors = 0 em0: Crc errors = 1 em0: Alignment errors = 0 em0: Carrier extension errors = 0 em0: RX overruns = 185231 em0: watchdog timeouts = 0 em0: XON Rcvd = 0 em0: XON Xmtd = 0 em0: XOFF Rcvd = 0 em0: XOFF Xmtd = 0 em0: Good Packets Rcvd = 918214961288 em0: Good Packets Xmtd = 933147667144 pitman:~# uptime 2:54 up 247 days, 5:59, 1 user, load averages: 1,82 1,63 1,55 WBR, Vladimir
