Hi,

I'm experiencing a problem with the em driver in 5.1-CURRENT for my Intel 1000/Pro fiber Gbit adapter.

The following is recorded in the syslog:

Everytime it does that connectivity is lost for 2-3 minutes.

I have found a similar problem at http://lists.freebsd.org/pipermail/freebsd-stable/2003-April/000539.html but that problem seems to be solved long ago, and the fix described in the thread doesn't help me.

I have tried to use some older drivers, but none would solve the problem.

Does anyone have an idea how to solve this?

Thanks in advance!
