ago days of Soekris 5501s, had
hw.ata.ata_dma=0
hw.ata.atapi_dma=0
OK,
Some more odd things going on. If I write to a file from dd some random
junk, not all of the file is saved when I do an unmount. This seems to
be specific either to the ata controller of the APU or to the msata disk
as I tested on a regular server with plain old disks and no issue

I was trying to create a single partition on a 16G mSata drive and
whenever I add a partition, all of a sudden the secondary GPT partion is
borked. Any idea whats going on here ?
0# gpart destroy -F ada0
ada0 destroyed
0# gpart create -s GPT ada0
ada0 created
0# gpart add -t freebsd-ufs ada0
