Hi,
On my home router, since a year or two I've occasionally seen watchdog
timeouts on re0 (which is connected with 1Gbps to a Cisco switch):
re0: watchdog timeout
They weren't frequent, but when they occurred it was always under high-ish
throughput (300-400 Mbps). Yesterday however, one particular download from
a machine on the LAN was able to consistently and repeatedly trigger a
watchdog timeout. Starting the download resulted in a watchdog timeout within
a second or two. It only stopped when I configured the downloading program
to limit itself to ~40 Mbps or so. This was surprising, since I regularly
can download stuff at 300-400Mbps.
I've been trying things like switching gige master/slave mode and enabling/
disabling ethernet flow control. While this was all nicely shown in the
output of ifconfig, it did not make any difference in symptoms.
Is such a watchdog timeout always caused by the NIC, or could it also be
caused by things like VLANs or an incorrect queue configuration? In other
words, is it useful to try different configurations or is this a clear
indication the the NIC itself is on its way out?
Output of ifconfig and dmesg follows:
