Greetings all,
Sorry for the hefty cross-post... I've been digging through
archives, and it seems that there was talk of this on -current
late October of 2000, including speculation that this was an
SMPng issue.
I'm running a D-Link DFE570TX four-port dc (21143xx, where xx is
TD if memory serves) on a dual-PII Micronics PTSAM motherboard.
See /var/run/dmesg.boot following .signature for details.
After my machine runs successfully for some while, I receive
continuous "watchdog timeout" messages on a 10baseT/UTP HDX dc
port. It doesn't seem to happen on 100baseTX FDX ports; however,
being an infrequent event, I cannot vouch for the statistical
validity of this claim.
Once I receive these timeouts, "netstat -I dc3 -w 1" shows an
output error each time I try to send traffic. A reboot is the
only "cure" that I have found... i.e., it's not a cable issue.
I don't recall experiencing this 4.3-R; I believe that I used the
same motherboard for three months under 4.3-R, and that this is
a new event since upgrading to 4.4-R. However, I'm a bit fuzzy
on this, too.
Anyone have any ideas?
Please keep me CCed. I'm not currently subscribed. My email
address is valid. However, please un-CC lists as appropriate --
if this is an SMP issue, I don't want to chew up -net, or vice
versa. Again, I apologize for the large crosspost, but it's
unclear to me which avenue is the correct one...
TIA,
Eddy
