I left the cable unplugged over night. Plugged it in this morning and the interface worked properly. It worked fine for an hour while I watched and poked at it, passed IPv6 packets fine, picked up IPv4 D= HCP, forgot to test otherwise. Then I downed the realtek interface and things se= emed to stop working on the intel interface as well. Downed and upped the intel interface and it came back to life, but the link state flapping started aga= in. Trying all the usual things isn't making it go away again either. Per Compri, I am using 64bit OS, not seeing Interrupt Storm messages, don't think it's interrupt rate related as there is hardly any traffic flowing wh= en this starts, but I did try upping the setting, which had no effect. --=20 You are receiving this mail because: You are the assignee for the bug.=
