When I have powerd > enabled, I frequently get a message on the console about 'vge watchdog > timeout' I got that similar one when using "powerd -b min" and transferring big file with ndis vap configured in adhoc mode. Probably I was just lucky that I used min instead of (h)adp. > Does anybody have any ideas on how to try and fix this issue? One nasty fix would be disabling kernel messages on console. I never tested if it actually works, or perhaps I did but forgot about it ;) : echo "kern.consmute=1" >> /boot/sysctl.conf Another, better one would be to make syscons giant free, perhaps rewriting it from scratch .... -- Paul
