e1000 problems from auto-negotiation phase
Hello,
I am looking into an issue where roughly 75% of the time the e1000 will come up speed=1000, but every once in a while it
doesn't. A couple differences in the syslogd are copied below. I attach output from slogger as well. While there is
output in syslog indicating that the DHCPDISCOVER is started (and a timer setup) there didn't appear to be any packets
leaving the interface on the client in the bad case. According to the output from slogger in the bad case, there's this
auto negotiation value of 4 (where it is 0 in the good case). In both cases I saw output "Link Down" where in the good
case this is followed by details of the link, but in the bad cause it fails.
Since I started seeing the differences at the autoneg phase, I could use a hand to determine what exactly was happening,
whether the differences in the values indicated an issue with the link or whether this was an issue with the driver.
syslog bad case:
[snip]
Aug 27 02:37:30 nto dhclient: DHCPDISCOVER to wm0
Aug 27 02:38:30 nto dhclient: Could not reach a DHCP server by specified timeout. Exiting

syslog good case:
