    SubjectAlsa oops, 2.6.0-test8
    2 oopses, both alsa, different scenarios, different traces in syslog:
    2.6.0-test8+kraxel-1 from bytesex.org (possibly not relevant - this seems to be an alsa oops)
    Sound card is ES1371.
    (I have downloaded 2.6.0-test11+kraxel-1, but haven't rebooted yet. I will
    try the same avi files, to see whtehr I can reproduce...)

    The first time, I was recoding /dev/dsp, and doing a debian dist-upgrade at the time. I
    didn't notice the oops until I next tried to play something a day later. The recording was
    complete, despite the oops half way through. The mplayer process segfaulted, but I thought at
    the time that might have been due to a corrupted .avi file. But I was just found out that the
    oops is repeatable at least on that file. This time, a hard lock.

    The second time, I was using esdplay to play an .au file, and it segfaulted, and the kernel
    hung hard. alt-sysrq s,u,b didn't seem to flash any hd lights, but the oops made it to syslog:
