When using a Digi/570i card in place of a dedicated router, the O/S will freeze up after a while. The last few lines in the kernel message buffer look something like: Mar 6 18:46:47 cpmail /kernel: ar0: Receive error chan 0, stat a4, msci st3 b, rxhind 1, cda 400a, eda43a2. Mar 6 18:46:47 cpmail /kernel: ar0: Receive error chan 0, stat a4, msci st3 b, rxhind 2, cda 4014, eda 4000. The machine has to be hard-reset after this to bring it back up. >How-To-Repeat: It seems to happen after some time. It doesn't appear to be related to heavy load, but presumably there must be *some* load. On the machine in question, it has happened twice this month. If this was a panic followed by a reboot it wouldn't be quite as bad, but freezing up is very undesirable behaviour, especially as this machine acts as a mailserver. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
