I'm pretty sure I compiled this from the ac17 patch, but the kernel says ac16.
Not sure who's right. I can get this oops reproduceably somewhere in the course
of mounting a minix floppy and untarring files to a ramfs disk.
Processor is an Athlon 600MHz.
dmesg shows this:
===============================================================
Freeing unused kernel memory: 208k freed
VFS: Disk change detected on device fd(2,0)
MINIX-fs: mounting unchecked file system, running fsck is recommended.
