[OOPS] 2.4.14 in USB? Appletalk?

[Michael Rothwell]

This oops is from booting a RH 7.2 system after installing 2.4.14 +
ext3.

[root@gromit rothwell]# kgcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs
gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)

This is an Athlon system, but I compiled a 386 kernel, for use in
another device.
