Running mkfs to build an xfs filesystem after a partition has
been mounted as ext2 has periodically failed for me. The failure
is usually this:
[root@lord /]# mkfs -t xfs -f -l size=16000b /dev/sda4
meta-data=/dev/sda4 isize=256 agcount=8, agsize=149104 blks
data = bsize=4096 blocks=1192826, imaxpct=25
= sunit=0 swidth=0 blks, unwritten=0
naming =version 2 bsize=4096
log =internal log bsize=4096 blocks=16000

A couple more data points:
o I was running a debug version of mkfs, it does not dump
core, just exists.
o running ltrace crashed the system in a copy_from_user writing
to the block device.
This may have more to do with the state ext2 leaves the block
device than anything else. I seem to recall that they deliberately
do not purge cached data on unmount (flush yes, thow away no).
Not sure what this might have to do with it though.
This does appear to be repeatable on my box though.
