freebsd stable - Jan 2011 - Supermicro Bladeserver

I am trying to track down a problem being experienced at icir.org using
SuperMicro
bladeservers, the SERDES 82575 interfaces are having connectivity or perhaps
autoneg problems, resulting in link transitions and watchdog resets.

The closest hardware my org at Intel has is a Fujitsu server who's blades
also have
this device, but testing on that has failed to repro the problem.

I was wondering if anyone else out there has this hardware, if so could you
let me
know your experience, have you had problems or not, etc etc?

Thanks much for any information!

Jack

My machine has the following em(4) device and it has a autoneg
problem.  When I was using 8-stable kernel at 2010/11/01, it has no
problem.  But I update to 8-stable at 2010/12/01, the kernel is only
linked up as 10M.


em0@pci0:0:25:0:    class=0x020000 card=0x13d510cf chip=0x104a8086 rev=0x02
hdr=0x00
     vendor     = 'Intel Corporation'
     device     = '82566DM Gigabit Network Connection'
     class      = network
     subclass   = ethernet
