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?
