Pyun, something new about this issue. Today I got another instance of it, but with a new twist. In addition to all the usual symptoms I got a lot of messages like the following in console:
nfe0: discard frame w/o leading ethernet header (len 0 pkt len 0) and even couple like this: nfe0: discard frame w/o leading ethernet header (len 4294967295 pkt len 4294967295) nfe0: discard frame w/o leading ethernet header (len 3 pkt len 3) Maybe these messages could give a hint about what was going wrong in nfe. on 04/07/2008 00:26 Andriy Gapon said the following: > > As they say - long time, no see :-) > I am back with some more details, but still with no insights. > > Let me refresh an essence of the issue. > The issue: after 'abrupt' reset/reboot of a system my nfe interface is > dead. > That is, if I do a graceful reboot (e.g. via shutdown -r) everything is > ok, ditto if I do power-down (whether graceful or not) and the power-up. > The problem happens only if I press reset button and then boot up. > > Details. > The issue can not be reproduced with nve driver. > Moreover, when I reproduce the problem with nfe, then kldunload nfe > driver, kldload nve driver - nve interface is alive.
