Greetings folks,
I am using 2 dmfe compatible cards on my computer for a while. But in
recent linux version (starting from 2.6.15 I think), I cannot work with
the two cards plugged at the same time. Note that I am using Linux for
several years with this hardware and that it used to work with 2.4.x
series and with some kernels in the 2.6 series.
I am using the 2.6 kernels on a k7 machine with the debian kernels and I
know I have the same issues with kernels (debian names):
linux-image-2.6.17-2-k7, linux-image-2.6.16-1-k7 and
linux-image-2.6.15-1-k7.
Also tried with a Mandriva 2007 image (2.6.17), same results.
The lspci -v output gives me the following:
00:0b.0 Ethernet controller: Davicom Semiconductor, Inc. 21x4x DEC-Tulip
compatible 10/100 Ethernet (rev 31)
Subsystem: Unknown device 3030:5032

I/O ports at de00 [size=256]

00:08.0 Ethernet controller: Davicom Semiconductor, Inc. 21x4x DEC-Tulip
compatible 10/100 Ethernet (rev 31)
Subsystem: Unknown device 3030:5032

When I load the dmfe module, I have the following lines:
# modprobe dmfe debug=1
dmfe: Davicom DM9xxx net driver, version 1.36.4 (2002-01-17)
dmfe: dmfe_init_one() 0
ACPI: PCI Interrupt 0000:00:08.0[A] -> Link [LNKA] -> GSI 9 (level, low)
-> IRQ 9
dmfe: dmfe_get_stats 0
eth0: Davicom DM9102 at pci0000:00:08.0, 00:80:ad:7f:70:1c, irq 9.
dmfe: dmfe_init_one() 0
ACPI: PCI Interrupt 0000:00:0b.0[A] -> Link [LNKD] -> GSI 11 (level,
low) -> IRQ 11
PCI: Unable to reserve I/O region #1:100@de00 for device 0000:00:0b.0
dmfe: Failed to request PCI regions
ACPI: PCI interrupt for device 0000:00:0b.0 disabled
The second card is not working then. But if I plug only the second card,
it works and the card initialize properly.
I don't know if you have enough information, let me know if you need
further details or testing.
Thanks for your work.
Best Regards.
