Managers,

First of all, thanks to all of those who took the time to respond. Your feedback
is appreciated. The bulk of the reponses suggested disabling autonegotiate on
the adapter and hardwiring the speed and mode. It was also suggested to do the
same on the port side. Below are examples of running the commands by hand
followed by the lines for making it permanent in the kernel. So far, we've
tried several variations without making any progress. Therefore, we've filed a
problem report with Sun. I'll post any additional information I get. Thanks
again for the help.

Mike

Set to 100mbs, half duplex, auto_negotiate off:

ndd -set /dev/hme adv_100fdx_cap 0
ndd -set /dev/hme adv_100hdx_cap 1
ndd -set /dev/hme adv_10hdx_cap 0
ndd -set /dev/hme adv_10fdx_cap 0
ndd -set /dev/hme adv_autoneg_cap 0

(Build into kernel via /etc/system)
set hme:hme_adv_100fdx_cap = 0
set hme:hme_adv_100hdx_cap = 1
set hme:hme_adv_10fdx_cap = 0
set hme:hme_adv_10hdx_cap = 0
set hme:hme_adv_autoneg_cap = 0
