There are more problems, -currently it has problems with pnp cards, ep0: <3Com 3C509-TPO EtherLink III> at port 0x300-0x30f irq 10 on isa0 ep0: No irq?! ep0: ep_alloc() failed! (6) device_probe_and_attach: ep0 attach returned 6 ep1: <3Com 3C509B-TPO EtherLink III (PnP)> at port 0x210-0x21f irq 5 on isa0 ep1: Ethernet address 00:10:5a:9e:71:b1 I have only ONE card in there, with only "device ep0" in the config. And yes I also see the performance problem.. I'm sorry to say so, but the ep driver has never been this broken before... -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
