Hello
I have some problems with 3Com nics, after a upgrade from 5.5-STABLE to
6.4-STABLE.
This machine has two 3com nics (one is LAN other is WAN) and i see too much
"watchdog timeout" on both cards.
This on/off up/down on cards, affect the interrupt to clients that are
downloading from apache web server, especially on large files.
--------------------------------------------
xer:/root# dmesg
xl1: watchdog timeout
xl1: link state changed to DOWN
xl1: link state changed to UP

---------------------------------------------
Another doubt would be my kernel config, maybe there is something wrong that
i cannot see, i'll post at the end of this post, 'cause is too long.
As you can see, the cards are 3c905C-TX model.
Someone told me to change drivers, but i cannot understand this advice.
I got same errors with same cards but with another mainboard, same problem,
watchdog appears after an upgrade from 5.4-STABLE to 6.4-STABLE.
I don't think that to change nic's pci slots, will solve the problem, i
think that maybe change the nics would resolve the matter, but i cannot
access to both FreeBSD phisically, cause the boxes are too far from me
(about 3500 km).
I'm asking you some advices, and i can i fix this problem.
p.s. with both 5.4 or 5.5 old kernel, the nics was fine.
Regards
Xer
