Hi,

I'm having lots of difficulties with BCM5719, which is the default
network card of HP Proliant DL 360 G8 servers. I can get a few ping
replies before I get a couple of these:

bge0: watchdog timeout -- resetting                                             
bge0: watchdog timeout -- resetting                                             

Then everything hangs. Can not log in using ssh.

I'm running: FreeBSD-9.0-RELENG_9-20120701-JPSNAP-amd64

Info about the NIC:

Searching other bug reports and posts, I've tried:

hw.bge.allow_asf="0"                                                            
hw.pci.enable_msi="0"                                                           

But it didn't help. Any ideas?

If I don't use the loader.conf settings above, I also get (before the
watchdog timeouts):

bge0: 2 link states coalesced                                                   
bge0: 2 link states coalesced                                                   
bge0: 2 link states coalesced                                                   

Best regards,
