Thanks. Have no cgd's or ccd's, though. This is just a vanilla
RAIDframe config w/ 2 disks in a RAID0 mirror config, root on raid0a,
booting the std NetBSD way (i.e. no grub or anything). Still looking
for causes for the dirty parity.
Apart from the parity everything is working just fine, but it would
be nice to figure out what I'm doing wrong.
