    SubjectRe: bttv problems in 2.4.0/2.4.1
    Do you have framebuffer console compiled into your kernel? I noticed
    similar behavior on my system when I had framebuffer console compiled in,
    ACPI or APM (cant remember which, probably ACPI) compiled in, and bttv as
    modules. System would power off when ACPI was loaded. Other times it would
    do other stupid things like hang abruptly for no apparent reason.
