Ahhh, do you know of an ethernet issue with this board? On certain small packets I get: epe0: ed_stat: 0x92000009 mbuf: 0xcb433300 len: 80, next: 0, 2, 00-00-5a-99-78-c4-00-d0-69-40-04-fa-08-00-45-00-00-42-15-24-00-00-40-11-e4-00-c0-a8-00-35-c0-a8-00-01-f7-e9-00-35-00-2e-52-80-88-bc-01-00-00-01-00-00-00-00-00-00-07-64-79-6e-61-6d-31-34-08-66-75-6e-6b-74-68-61-74-03-63-6f-6d-00-00-1c-00-01 epe0: ed_stat: 0x92000009 mbuf: 0xcb432700 len: 80, next: 0, 2, 00-a0-c9-31-30-5e-00-d0-69-40-04-fa-08-00-45-00-00-42-15-2f-00-00-40-11-e3-e8-c0-a8-00-35-c0-a8-00-0e-d0-1b-00-35-00-2e-7a-41-88-bc-01-00-00-01-00-00-00-00-00-00-07-64-79-6e-61-6d-31-34-08-66-75-6e-6b-74-68-61-74-03-63-6f-6d-00-00-1c-00-01 The first line is the TX status register indicating a carrier loss and a underrun... The second is the data packet.. it's a reverse dns query iirc... I'm at 100mbit and full duplex, so a collision shouldn't of happened... The wierd part is that this is durning boot up while running w/ a nfs mounted root.. I can also read/write about 2meg/sec over nfs w/o any issue, but do a simple 80 byte dns query, or try to send an icmp packet, and I get the above... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
