Sometime, even if a lot of file transfer, there is nothing happened. While sometime, when I check the log, a lot of error in it. And in daily mail, before the ftp was used heavily, there were tens of IErrs, while after, there are thousands of. > >Fix: > I use current on another machine which has the same problem when use 5.2.1, and ... I think, the problem does not occur till now. I had the same problem on my Ultra2 which runs -CURRENT. The real cause of the problem seems to be the lack of auto-negotiation capability of hme(4). According to the commit logs from Marius, hme(4) with DP83840A PHY has the problem. I fixed the problem by reviving commented code. Activate "mii_mediachg(sc->sc_mii);" statement located at line 822 of sys/dev/hme/if_hme.c(rev. 1.27) if your system is NOT "Netra t1 100". If your system is "Netra t1 100", your best bet would be half-duplex with some kind force mechanism. Hope this helps. Regards, Pyun YongHyeon -- Pyun YongHyeon <http://www.kr.freebsd.org/~yongari>;
