Yes, one in particular is Cisco switches will not see an autonegotiate
preamble on the wire and will default to 100-half if they are set to
autonegotiate. I
heard alot of whining from idiots on that one (la, la, la, Solaris sucks,
your machine is broken). Tell them what I found and what the fix was,
then they say, "Oh yeah, that guy moved offices a week ago."
