I've plugged for testing a 3C996-T in a 32-bit slot on my Athlon system lspci -v gives for the unused card:

00:09.0 Ethernet controller: BROADCOM Corporation NetXtreme BCM5700 Gigabit Ethernet (rev 12)
Subsystem: 3Com Corporation 3C996-T 1000BaseTX
Flags: bus master, 66Mhz, medium devsel, latency 64, IRQ 11
Memory at effe0000 (64-bit, non-prefetchable) [size=64K]
Capabilities: [40] #07 [0002]
Capabilities: [48] Power Management version 2
Capabilities: [50] Vital Product Data
Capabilities: [58] Message Signalled Interrupts: 64bit+ Queue=0/3 Enable-

If I access the card with the broadcom driver bcm5700 from 2.4.18 everything works fine (just brief testing). But using the Tigeon v0.97 I cannot send any data to the network.

A modprobe of bcm5700 gives:
Broadcom Gigabit Ethernet Driver bcm5700 with Broadcom NIC Extension (NICE) ver. 2.2.8 (03/07/02)
AMD756: dev 14e4:1644, router pirq : 2 get irq : 11
PCI: Found IRQ 11 for device 00:09.0
Cannot get MAC addr from NVRAM. Using default.
VPD read failed
eth1: 3Com 3C996 10/100/1000 Server NIC found at mem effe0000, IRQ 11, node addr 001018686176
eth1: Broadcom BCM5401 Copper transceiver found
eth1: Scatter-gather ON, 64-bit DMA OFF, Tx Checksum ON, Rx Checksum ON

A modprobe of tg3 gives:
tg3.c:v0.97 (Mar 13, 2002)
AMD756: dev 14e4:1644, router pirq : 2 get irq : 11
PCI: Found IRQ 11 for device 00:09.0
eth1: Tigon3 [partno(BCM95700A6) rev 7102 PHY(5401)] (PCI:33MHz:32-bit) 10/100/1000BaseT Ethernet 00:04:76:3b:39:c7

And after ifconfig eth1 I get:
eth1: Link is up at 100 Mbps, full duplex.
eth1: Flow control is on for TX and on for RX.

But no packets go over the card - and sometimes the whole system freezes. Is there some kind of problem with plugging the card into a 32-bit slot? The same card worked with no problems in a 64-bit slot..

Any further debugging that I can do?

It's an amd756 chipset bug. bcm5700 chooses to work around it in their driver, when it really belongs as a generic PCI fixup in the kernel.

What needs to be done for this? Can you point me to the PCI workaround in the bcm driver?

I only found via grep in the sources a workaround for the AMD 762 northbridge but nothing directly for the 756.

Thanks,
Andreas

bcm5700 works around AMD762 bug -- and that workaround should be in stock 2.4.18 and 2.5.7 kernels now as a PCI quirk. I think something else is going on here...

Its not IMHO a chipset bug either. The documentation on the 762 is quite explicit. It has a nice table and makes it absolutely clear which modes are PCI 2.2 compliant.

Andreas,
can you e-mail full 'lspci -vvv' run as root?

Hi Jeff,
