Hi,

I'm seeing similar symptoms with NanoBSD images on PCEngines ALIX and
APU2 boards, using compactflash and SD card storage respectively. The
problem has appeared as soon as I started testing 11.1-BETA1 from the
stable branch.

Problem appears when I update the image, using a slightly modified
version of the standard nanobsd update and updatep[12] scripts. My
changes are not in the dd/gpart commands though, which are the same.
gpart seems the most likely candidate though.

I have just discovered this thread and I will test reverting r318394
soon. Thanks to Peter for narrowing it down!

Maybe this is related to having the disks mounted read-only?

Should I open a bug report to properly track this down?
