Hello all,
I have a 2*PentiumPro200 PC with FreeBSD 5.3 acting as a firewall in a
department network.
The PC has both IDE and SCSI hard drives.
(Quite strange system for a firewall, isn't it? However, it was the most
suitable box I was able to find).
It has 3 NICs xl0,fxp0 and fxp1.
>From time to time both fxp's SIMULTANEOUSLY stop working and produce
messages fxp*: device timeout.
After doing ifconfig fxp* up& down it said
Dec 22 19:22:13 firewall kernel: fxp1: SCB timeout: 0x70 0x0 0x50 0x0
Dec 22 19:22:13 firewall kernel: fxp1: SCB timeout: 0x20 0x0 0x50 0x0
Dec 22 19:22:23 firewall last message repeated 53 times
Dec 22 19:22:23 firewall kernel: fxp0: SCB timeout: 0x70 0x0 0x50 0x0
Dec 22 19:22:23 firewall kernel: fxp1: SCB timeout: 0x20 0x0 0x50 0x0
The system resumes normal operation only after system reboot.
xl0 does not experience any problems.
Does anybody know how to avoid this?
Many thanks in advance.
Here is the output of pciconf -l -v
