Description

Problems beginning some time after mount on line beginning with "(da8". This is
a new version 2 hammer partition made and used on freshly updated system on
ThinkPad X31 laptop. Same kind of error and messages have appeared with a
different external drive (older hammer partition, older installation) on a
different DragonFly install as well, as well as when trying to use its even
older installation CD (which was an old 09-02-06 snapshot) live as well as
trying to install with HAMMER on said different external drive (for later manual
adjustment and use in laptop).

No such problem with other filesystems, no problem (ever) with HAMMER on
non-external drives.

For log below (until a first incident), these messages with which the problem
begins keep repeating if trying further use. Unmounting and re-mounting gives
some time (though much data written during previous mount lost) before it
happens again in the same way.

Everything works until the
