The kernel is from a SUP of less than 12 hours ago. Things went from
"ok" to "lousy" as soon as I rebooted.
The CVS log indicates that there have been 2 recent changes based on
BCM5701 errata.
I suspect that this is hosing the 5700.
----------------------------
revision 1.3.2.28
date: 2003/09/26 16:02:04; author: ps; state: Exp; lines: +1 -1
MFC rev 1.55
By not setting No_CRC in the Mode Control Register, we must also
reduce the size of the packet by 4 bytes to remove the ethernet crc.
Approved by: re
----------------------------
revision 1.3.2.27
date: 2003/09/23 02:34:49; author: ps; state: Exp; lines: +1 -2
MFC: rev 1.54, Do not set the No_CRC bit in the Mode Control Register.
Tomorrow, I will pull out the revision prior to those changes and see
if it fixes it.....
