The machine I've been testing on has three ext2 partitions on it. In
the course of narrowing down what triggers this bug and testing patches,
I'd successfully made three ext2 filesystems (when / (sd0a) was mounted
without 'log') on different partitions -- none of which was ever ffs
Typically I've been running mke2fs on just one of the ext2 partitions,
but I was in a situation where I had booted with log enabled on / and
had mounted one of the other ext2 partitions. When finished, I
unmounted it and (to my surprise) caused a kernel panic. Up until that
time I'd only been running mke2fs to trigger the panic.
