Hi, As the subject states I have been seeing hangups on a machine with that chipset [1] when using default ifconfig settings. It was hanging once every day on average. Following suggestions I found googling I have disabled tso4 and the machine has been running smoothly for weeks. I don't have any strict requirement to enable tso4 on it so I'm ok with things as is, but I'd like to help debug and resolve the problem. How can I help with this? Any pointers to specific data I can collect which could be useful? Thanks! [1] em0@pci0:0:31:6: class=0x020000 card=0x86721043 chip=0x15b88086 rev=0x31 hdr=0x00 -- Guido Falsi <mad@madpilot.net>
