What I have seen is the card does lots of interrupts after three-four hours of workload in some machines. I've seen more than 70000 ints and my onboard SCSI response time went very slow. The machine was idle, as in your case. I personally blame the tx driver for all the faults as the card works very well under NetBSD. Under FreeBSD the autonegotiation doesn't work reliably, opposed to NetBSD. Perhaps the MII bus from NetBSD will help, unfortunately the tx driver wasn't converted yet. -- Vallo Kallaste vallo@matti.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
