PROBLEM: Athlon-optimized 2.4.4pre7 still won't boot.

["Bobby D. Bryant" <bdbryant@mail.utexas.edu>]

I have an Athlon + VIA system that would never boot an Athlon-optimized
2.4.3[-ac*], and just FYI, it will not boot an Athlon-optimized
2.4.4pre7 either.

It does compile without errors, and an otherwise identical i686 kernel
boots and appears to run fine.

With the Athlon kernel I get a flood of boot-time error messages that
streams off the screen, so I do not know exactly what the trigger is; it
ultimately hangs without completing the boot.

I have tried a couple of times with different compilers, and I notice
that sometimes it gets past the point of mounting the disks, and other
times it does not get that far.

The tail of the message on my most recent try is:

    Kernel panic: Aiee, killing interrupt handler!
    In interrupt handler - not syncing

The most basic poop follows.  If this is news, I'll be happy to provide
however much more detail you require.

Thanks,

Also, the "kgcc" hack gives the same result:
