Poking around, I discovered that the card is no longer correctly identified; it now 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 Using a stock Debian kernel (2.6.32-5-686), it shows up (and works) correctly: 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 What on earth is this all about? I tried another kernel I had lying around, 2.6.37-rc6-lizzie-00132-g55ec86f (built from kernel.org vanilla sources), and it also works fine. I can do a bisection if necessary, but I figured I'd check here first.
