Tx underruns with 1.2 RC4 - NIC problem ?
-
running pfsense 1.2RC4 on a Dell Optiplex GX240 with HDD and 1 GB RAM.
Using the onboard NIC (3com 3c905) and a PCI ethernet (Accton MPX 5030/5038 10/100BaseTX).XL0 = 3c905
RL0 = AcctonMachine stop responding with this message on console:
xl0 watch dog timeout …I restarted the box:

I found many threads regarding this issue with the 3COM NIC.Prior to this, I was running 1.2 RC3 for weeks without any errors.

i had that same problem
i had a setup with a dell optiplex 180
1ghz processor
512 ram
20gb hd
1 3com on board nic
and 2 3coms installed on a dell riser board.it would work for 8hrs and then quit.
i ended up throwing out that old machine and using a older machine in its place
900mhz amd athlon
768 ram
same hd
and 3 pci 3com cards.
2 of them are from the old machine. since i put the new hardware in place the only issues i get are just tx underruns every once and a while but nothing that shuts the machine down like a brick.not sure if this helps but that is what i did to fix it.

I've disabled the onboard NIC on the Dell machine, removed the Accton NIC.
Put in 2 Intel NICs and no more issue.
So far it looks very good, system log is clean -
Hi,
I do have also have an pfsense 1.2 RC4 running. My problem is, that i am getting the well known "watchdog timeout – resetting" error on the network interfaces located on another PCI card. My setup:
2x onboard Ethernet interfaces (Intel chip)
2x Ethernet interfaces located on an Intel PRO 1000MT dual PCi/PCi-x cardall 4 interfaces (the onboard and also the one on the card) work very well under Linux (booted with a knoppix Linux 5.0 Live CD)
in pfsense 1.2 RC3 & RC4 i got these message on console: "em0 watchdog timeout -- resetting" when i assigned an ipadress to the second Ethernet interface on the PCI NIC
The other Ethernet interface on the Card works well.I tried the following solution suggest - but with no success:
-disabled ACPI
-assigned other IRQ
-disabled PnP
-changed NIC manufacturer (Used a dual compaq NIC PVI-64bit insted of the intel)
-changed PCI slotI started etherreal on my notebook and saw, that the "broken" ethernet port on the NIC is able to send ethernet packets, but not able to receive them.
I started a "ping" on the serverIt would be great if somebody could give me an iditional hint how i could try to solve the problem
thanking you in advance for helping meregards,

Watchdog happends when you have problems in hardware!
It might even happen from wrong configured multicast filter on the nic.
This are hardware/driver issues. But mostly it means the hardware is not behaving well.
From your config i suspect that you have pci slots(the onboard ones) which are sharing irq so you can not really do much about it.
Just use something else. -
Try to disable all onboardhardware that you don't need (printerport, second serial ports, soundcard,…) to free some resources. Also remove any unneeded pci-hardware that you might have in there. Then reset your bios hardware assignments and reboot and see if you somehow manage to get your nics to not share irqs.
-
One last thing you could try is to load the multiprocessor kernel instead of the uniprocessor kernel. If you were already running mp, then never mind.

thank you very much for your help - now it works :)
i now did a bios update and disabled really all hardware, that is not needed (e.g. USB support)
its great that i am now able to use the pfsense on that hardware instead of some linux firewall,
because only pfsense supports features like CARP and pfsync
so it seams to be an IRQ issue
thanks again,malcom
