Please show the output of `ifconfig -a' when you notice this problem. Finally, try `ifconfig down' followed by `ifconfig up' when you notice this, and see if it temporarily fixes the problem. Thanks to Matthew Dodd and NetBSD, I think we may have a solution to the ep wedging problems (which has similar symptoms, by the way) sometime soon (i.e. when I get around to it this weekend, after first mid-term, if noone beats me to it). In the meantime, it would be nice to know if there are other devices exhibiting this behavior. (All this assuming, of course, that what you're describing is not the result of a kernel resource shortage, such as mbuf starvation, etc.) Regards, Bosko.
