3Com PCI 3c905B Cyclone & 3c905 Boomerang on 2.6 kernel = not working!


I'm running Fedora Core 1 with kernel 2.6.7 with the latest patches installed. I have two problems.

First of all I had to disable Kudzu to be able to get networking up at all... I have two 3com-cards.

Here are the errors before disabling Kudzu:

Second problem is that I get a lot of RX- and Frame errors on my external interface, which is connected to a cable modem, when I try to download anything from the internet from my internal network. Speed should be about 200kb/s max, but it's as low as 10k/s.

The two cards:
Index #1: Found a 3c905 Boomerang 100baseTx adapter at 0xe400.
Index #2: Found a 3c905B Cyclone 100baseTx adapter at 0xe800.

Operating at:
eth0: negotiated 100baseTx-FD, link ok (connected to internal 100mbit/FD switch)
eth1: 10 Mbit, full duplex, link ok (connected to cable modem)

As you see, frame and RX errors are the same.. and keeps going up when I transfer files from my 100mbit net out through 10mbit NIC.

All my internal machines work fine over 100mbit localnet, except when they connect to the internet, speed is terrible.

My switch detects all NIC:s as 100mbit autoneg. The cable modem isn't connected to the switch, but to the external interface of my box, eth1. The cable modem doesn't support autoneg.

Any ideas? If I set 10mbit on the internal net, it would probably work? I rather have 100mbit.

Appreciate any help !

Thanks

I don't know if this will help or not, but I'd suggest 2 things: first, be sure the 3c59x modules are actually being loaded, which can be confirmed by running the lsmod command as root. If they aren't there, as I expect you know you can manually load them via the insmod or modprobe command. I've got a Cyclone card, and at least for me, it wasn't being loaded automatically at the start, which caused the same kind of problem as you described.

Second, what are the results of running ifconfig? I don't see that there's a INET address value being shown for either eth0 and eth1 (which of course would be the case if they weren't working) and therefore I'd also suggest trying to just bounce the interface:
Code:
ifconfig eth0 down
ifconfig eth0 up
Let me emphasize that these may not solve the problem, but if nothing else, they could be 2 factors that you could eliminate from consideration as being the cause. In any event, good luck with it. -- J.W.

Thanks for your suggestions.

I removed the inet to not expose my IP:s. Sorry for the confusion

lsmod output:

Code:
# lsmod
Module                  Size  Used by
3c59x                  34344  0
I suspect my first problem is caused by an old bug, which apparently wasn't fixed correctly. I think the problem lies in Kudzu having a conflict with the 3com driver.

Doing a quick search on '"FIFO diagnostic register 2000" + kudzu' gives a couple of references to this old bug (note posts on Redhat.com forum), and the posted solutions are to disable Kudzu until this has been fixed.

It's weird that no patches came out since this is an old bug.

My next real problem is the frame and RX errors:

Code:
# cat /proc/net/dev
Inter-|   Receive                                                |  Transmit

    lo:       0       0    0    0    0     0          0         0        0       0    0    0    0     0       0          0
  eth0:  433006    3001    0    0    0     0          0         0  2396986    3053    0    0    0     0       0          0
  eth1: 6705078   74846  172    0    0   173          0         0   416756    2795    0    0    0     0       0          0
Note 'errs' and 'frame'. Anyone know what causes these errors?? Very little information on google on this.


Thanks
