Hi list,
Celejar (see message copied below) has been having problems with his
Broadcom BCM4401-B0 Ethernet card not working on very recent kernels -
it seems to be sporadically registered either as the correct device or
as a completely different Broadcom device on a different subsystem and
IRQ.
He has emailed various mailing lists and, more recently, linux-kernel,
netdev, devel.linuxdriverproject and the b44 driver maintainer but so
far without any response.
I would need to do a _lot_ of swotting up on device registration
semantics to even know where to start looking, so can anyone here
help? Any ideas?
NOTE: _please do_ cc him as I don't think he is subscribed to kernelnewbies.
Cheers
Julie

[I have previously posted this issue to the Debian user, lkml and
netdev MLs, but no one has replied with any suggestions. It has been
suggested that I try these addresses.]
Hi,
With recent kernels (git pulls of vanillas sources from kernel.org,
mainline and 2.6.38.1), my Broadcom BCM4401-B0 Ethernet card, normally
driven by the b44 driver, has stopped working. Poking around, I
discovered that the card is (sometimes) no longer correctly identified;
it now (sometimes) shows up (with 'lspci -v' as root) as this bizarre
device:
06:01.0 Network and computing encryption device: Broadcom Corporation
Device 0010 (rev 02) (prog-if 10)
Subsystem: Allied Telesis, Inc Device 0010
Flags: fast devsel, IRQ 10
Memory at d0000000 (32-bit, non-prefetchable) [disabled] [size=8K]
Capabilities: [40] Power Management version 2
This is what it looks like when it's correctly detected:
06:01.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)
Subsystem: Acer Incorporated [ALI] Device 0090
Flags: bus master, fast devsel, latency 64, IRQ 21
Memory at d0000000 (32-bit, non-prefetchable) [size=8K]
Capabilities: [40] Power Management version 2
Kernel driver in use: b44
I'm currently seeing the problem with 2.6.38.1. What on earth is this
all about?
IIANM, the same kernel will sometimes detect the card correctly, and
sometimes incorrectly; this will make doing a bisection somewhat tricky.
Any suggestions, or further tests I should try, or information I should
provide?
Celejar
