I don't know it will eradicate the bug as I don't see the watchdog error on my system. The patch borrowed Yukon specific register definition from Linux driver and adopted Yukon FIFO related operations from Linux. I don't know exact meaning of the registers(it's just guessing) but it seems it doesn't hurt on my system. You may have to download 4 files to build the driver. http://people.freebsd.org/~yongari/sk/sk_test2/if_sk.c http://people.freebsd.org/~yongari/sk/sk_test2/if_skreg.h http://people.freebsd.org/~yongari/sk/sk_test2/xmaciireg.h http://people.freebsd.org/~yongari/sk/sk_test2/yukonreg.h -- Regards, Pyun YongHyeon
