I started this thread on current@ as Subject: 5.3-RC1 attempt with a Toshiba Libretto 70CT failed, 4.10 OK But it evolved to be ep0 intermittent on 4.10-RELEASE, so moved to mobile@. I don't know if Ruben de Groot <mail25@bzerk.org> is on mobile@ so please don't drop him off CC: unless he says he is. He has same problem I do.

I did a little testing: Now multi user on 4.10 I still see intermittent ep0 freezes: I've also tried 2 other ether cards since, another 3com 589, (with same external BNC & UTP transducer) & a 3com Office Connect 3CXSH572BT with an X Jack UTP connection: All cards behave OK with FreeBSD elsewhere, I've also tried with UTP & co ax, all my other hosts ping OK. > Pinging from the libretto to another system, both running tcpdump, would > give normal results on the other system (1 ICMP request arriving every > second, 1 reply being send back). > On the Libretto however, the replies would not show up in the tcpdump > trace for a long time, sometimes over 60 seconds, after which I would > see a "burst" of replies in a few seconds, but a lot of them never > showed up at all. > So it looks like the problem was in the receive side of the NIC/driver. I see on remote host (name=flip) with "tcpdump -i ed0 host lapl" both "icmp: echo request" * "icmp: echo reply" I see on libretto host (name=lapl) with "tcpdump -i ep0 host flip" just "icmp: echo request" Perhaps this means the interrupt on receive is lost ? > The hardware is fine btw; the Linux driver has no problems with this > configuration. I'm still learning /boot/loader.conf (copies of syntax I'm thinking of periodically go to http://berklix.org/~jhs/hw/toshiba/libretto.70ct/boot/loader.conf but I might even have correct stuff there, then delete again in error, it's hard to decide what belongs there.) I guess we need some loader.conf magic ! Warner or someone have some suggestions please ? - Julian Stacey. Unix,C,Net & Sys. Eng.
