    SubjectFried the onboard Broadcom 4401 network...

    I'm not exactly sure what caused this or if it's reproducable, but
    here's my story anyway.

    I have an ASUS A7V8X with onboard Broadcom 4401 (Rev 01) 10/100 and I've
    been running 2.4.x (2.4.21) for a long time now with Broadcoms bcm4400
    driver (v2.0.2) which has worked just fine. Now I decided to try 2.6 and
    installed 2.6.2-rc1-bk2 with the b44 driver that comes with the kernel.
    While doing some tests I noticed that I got really crappy performance
    (3-4MB/s) while sending, but full throughput (~11MB/s) while receiving.

    So I figured that it could be the shipped driver.. Downloaded bcm4400
    v3.0.7 which has 2.6 support and installed it. Didn't make stuff go
    faster. So I thought I'd boot into 2.4.25pre6 and see how it behaves
    under a 2.4 kernel with the latest bcm4400 driver. The 2.4.25pre6 I had
    compiled includes the b44 driver. I booted it up and then I got a bunch
    of the following:
    "eth0: b44: BUG! Timeout waiting for bit 80000000 of register 428 to
    followed by:
    "eth0: Link is down."

    After that, I have not been able to get link (neither see it through
    Linux/WinXP or the physical LED). I have tried multiple cables and my
    laptop is perfectly happy with all of them, but the broadcom thingie
    seems not. The switch doesn't see link either.

    The actual chip seems to be alive, it responds to PCI stuff... it can be
    initialized and all but I can't get link.

    Not sure what you can do with this information, but I can probably not
    do anything more with this NIC at least..

    CC me for any replies, please.
