As long as I do innocet stuff like ping everything seems to work. Once I transfer any useful data (i.e. make update, ssh, ftp, http, ...) The system responds (after approx 1 and 2 seconds) with de0: abnormal interrupt: transmit underflow (raising TX threshold to 96|256) de0: abnormal interrupt: transmit underflow (raising TX threshold to 128|512) and network transfer speed gets so slow I cannot even measure it. (Ping to my gateway on the local network takes 10 seconds and up.) By ifconfig de0 down|up I can reset the card and repeat as often as I please. The speed problem can be undone by setting debug.mpsafenet=0. Please tell me if I can give any diagnostics that might help. Or if I can test any patches You might work on.
