I was not sure which group I should post this too, being somwhat new
to FreeBSD, so I thought I'd start here and hopefully get some direction
if this is not the correct place.

I recent upgraded my LAPTOP from a DX2/66 to a DX4/100 and begin
getting

    ed1: remote transmit DMA failed to complete

After a number of these messages, the system would freeze up.

The problem seems to be related to 'maxwait' in the if_ed.c file.

I changed the two lines which read:

        int     maxwait = 100;   /* about 120us */

to

        int     maxwait = 100*100/66;   /* about 120us */

and this seemed to remedy the problem.
