  1. 2.6.24-rc6 oops in net_tx_action

    Kernel is 2.6.24-rc6 + linuxpps patches, which are all to the serial
    port driver.

    2.6.23 was known stable. I haven't tested earlier 2.6.24 releases.
    I think it happened once before; I got a black-screen lockup with
    keyboard LEDs blinking, but that was with X running so I couldn't see a
    console oops. But given that I installed 2.6.24-rc6 about 24 hours ago,
    that's a disturbing pattern.

    (N.B. I was pretty careful, but the following was transcribed by hand.)

    Kernel panic - not syncing: Fatal exception in interrupt


    Network config is a little complex; there are 5 physical network
    interfaces and a bunch of netfilter rules. A quad-port 100baseT Tulip
    card which provides "outside-facing" interfaces (two uplinks, a DMZ,
    and a spare), and a gigabit VIA velocity card for the internal network.

    The hardware has ECC memory (1 GB, kernel starts at 2.75G) and mirrored
    drives, and has generally been very stable for a long time, modulo some
    disk hiccups.

    The tulip drivers have been solid forever. The VIA velocity driver is more
    suspect; I made an effort a while ago to get tagged VLANs working on it,
    which was a notable failure. Still, this oops is in core network code.

    As you might guess, it makes people somewhat grumpy when the main
    firewall/router takes a dive, but I can experiment after hours.

    It is probably this one:

    Thanks! I got the patch from
    http://marc.info/?l=linux-netdev&m=119756785219214
    (Which didn't make it into -rc7; please fix!)
    and am recompiling now.

    Actually, I grabbed the hardware mitigation followon patch while I was
    at it. I notice that the comment explaining the format of CSR11 and
    what 0x80F10000 means got lost; perhaps it would be nice to resurrect it?

    0x80F10000
    80000000 = Cycle size (timer control)
    78000000 = TX timer in 16 * Cycle size
    07000000 = No. pkts before Int. (0 = interrupt per packet)
    00F00000 = Rx timer in Cycle size
    000E0000 = No. pkts before Int.
    00010000 = Continues mode (CM)

    (Boy, that tulip driver could use a whitespace overhaul.)

    Jeff is busy so he's asked me to pick up the more important
    driver bug fixes that get posted.

    I'll push this around, thanks.

    Much obliged. It's only 11 hours of uptime, but no problems so far,
    even trying abusive things like "ping -f -l64 -s8000".
