> I downgraded the system to the version from 03/01, it works fine; it might be interesting to mention that multimedia/obs, compiled on the version from 07/01, does not work on the version from 03/01, even if it reports the same 10.99.2:

$ uname -a

$ ldd /usr/pkg/bin/obs
ldd: /usr/pkg/bin/obs: invalid ELF class 2; expected 1

As far as I understand it, there was a change with the dynamic loader at this time? BTW, I tried backing out sys/dev/ic/igpioreg.h, as mentioned above, it didn't make any difference.
