There are spontaneous messages like that: ae0: Size mismatch: TxS:384 TxD:14900 ae0: Received stray Tx interrupt(s). ae0: Size mismatch: TxS:392 TxD:12336 ae0: Size mismatch: TxS:388 TxD:29285 ae0: Size mismatch: TxS:368 TxD:28270 ae0: Size mismatch: TxS:400 TxD:14896 ae0: Size mismatch: TxS:382 TxD:25445 ae0: watchdog timeout - resetting. or ae0: watchdog timeout - resetting. or ae0: Size mismatch: TxS:384 TxD:2573 ae0: Received stray Tx interrupt(s). ae0: watchdog timeout - resetting. After that messages appears on console and dmesg, interface doesn't respond. The only solution is ifconfig ae0 down && ifconfig ae0 up to make it work properly. This behaviour is unpredictable on time and appears both under mid-heavy load and in idle state (no internal connections). Also, according to message in http://forums.freebsd.org/showthread.php?s=3a2a2318a953d85109318a2ca26f24f0&t=11528 such behaviour seems to appear on FreeBSD 8. I believe that a problem in the driver, because OpenBSD with different driver implementation (lii) and ArchLinux with 2.6.33 kernel works well. >How-To-Repeat: Install FreeBSD 7.3 on AsusEEE 701, and just wait some time (from 2h to 48h). >Fix: >Release-Note: >Audit-Trail: >Unformatted:
