| |
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?
