It works with mtu at 1500. If I set mtu to 9000 and send a small ping (such as 32 bytes), it still works. But when I attempt to transmit a jumbo frame, by a ping -s 4000, the card drops into a state where no packet manages to get out anymore. Even a ping -s 32 does not work anymore. Sometimes it says: bge0: watchdog timeout -- resetting bge0: block failed to stop: reg 0xc00, bit 0x00000002 -- Emmanuel Dreyfus m...@netbsd.org
