[-- Attachment #1 --] > http://svnweb.freebsd.org/base?view=revision&revision=236216 > > Ok, confirmed after ~50 reboots. There is a timing problem in this revision that I don't fully understand. Adding printf's inside bce_reset() will cause the existing code to succeed, and sometimes the existing code in this revision will work (about 10% of the time). In the failure mode, the network interface, bce0, will not come up into service *without* and network restart, after which it works fine. I suspect that we are missing a DELAY or UDELAY somewhere in the restoral of the emac_status settings that needs to be implemented. Sean p.s. sorry for the late report as the commit is well over a year old.
