[OOPS] testing/prerelease of 01/03 on startup

[Tom Leete]

Hello,

kernel is 2.4.0-prerelease with testing/prerelease patch of Jan. 3, i486.
Oops is repeatable.

I caught this one on serial console just as init begins:

$ ksymoops -K -L -O -v /boot/vmlinux-2.4.0-prerelease -m
/boot/System.map-2.4.0-prerelease tleete.prerelease.oops
ksymoops 2.3.5 on i486 2.4.0-test13-pre4.  Options used
     -v /boot/vmlinux-2.4.0-prerelease (specified)
     -K (specified)
     -L (specified)
     -O (specified)
     -m /boot/System.map-2.4.0-prerelease (specified)

Everything is looged on the serial console machine, so if you need more,
it's here.

Hope this helps,
