[Efw-user] EFW in Xen-DomU: network interfaces missing after changing mainboard and CPU

[Ronald S. <ro...@sc...>]

Hello everybody...

I already asked this on efwsupport.com, but maybe this list is the
better way. Don't worry about this kind of cross-posting, if you have a
solution for me I'll post it to the forum and vice-versa. So everyone
profits. ;-)


I ran EFW for more than a year as a virtual machine under Xen (DomU).
There's a PCI quad-NIC in the system that is hidden from Dom0 and given
directly to the EFW-DomU.

Everything was fine until last weekend I changed the mainboard and CPU
in the computer. The quad-NIC has new IRQs now, and the PCI address
changed. I reconfigured my kernel boot line, and the configuration of
the Endian-DomU.

Now, with lspci I can see that there is the card visible for the Endian:

00:00.0 Ethernet controller: Digital Equipment Corporation DECchip 21140
[FasterNet] (rev 22)
00:01.0 Ethernet controller: Digital Equipment Corporation DECchip 21140
[FasterNet] (rev 22)
00:02.0 Ethernet controller: Digital Equipment Corporation DECchip 21140
[FasterNet] (rev 22)
00:03.0 Ethernet controller: Digital Equipment Corporation DECchip 21140
[FasterNet] (rev 22)



The driver (tulip) loads without error messages, in dmesg output I see:

Linux Tulip driver version 1.1.13 (May 11, 2002)
PCI: Enabling device 0000:00:00.0 (0000 -> 0003)
PCI: Enabling device 0000:00:01.0 (0000 -> 0003)
PCI: Enabling device 0000:00:02.0 (0000 -> 0003)
PCI: Enabling device 0000:00:03.0 (0000 -> 0003)



There was more output when the card still did work, but I don't have it
anymore. This is the similar output from my plain Debian test system:

Linux Tulip driver version 1.1.13-NAPI (May 11, 2002)
PCI: Enabling device 0000:00:00.0 (0000 -> 0003)
tulip0:  EEPROM default media type Autosense.
tulip0:  Index #0 - Media MII (#11) described by a 21140 MII PHY (1)
block.
tulip0:  MII transceiver #1 config 3100 status 7849 advertising 0101.
eth0: Digital DS21140 Tulip rev 34 at 0001ec00, 00:00:D1:1D:43:EF, IRQ
21.
PCI: Enabling device 0000:00:01.0 (0000 -> 0003)
[...]



But on EFW,  ifconfig doesn't show the interfaces (eth0 to eth3) anymore.

I tried giving the card to another virtual machine (plain Debian), and
there I can use the NIC without any problems. So I think there's
everything fine with the hardware and the host system. Somehow, Endian
did recognize the change in hardware and doesn't accept it.

What can I do?


Thanks in advance!


Ciao,
Ronald.
