Brian,
on a system where I routinely run both a 32-bit and a 64-bit x86
kernel (underneath the same 32-bit distro) I'm observing the
newly added message being issued, along with the mounts
subsequently failing when running the 32-bit kernel. Without
doing anything to the FS, running an older 32-bit kernel or a
4.5-rc6 64-bit one have everything work fine (and silently), so
I can only assume the detection logic doesn't work right in a
32-bit kernel. I've looked over commits 6528250b71 and
7088c4136f without being able to spot any obvious word size
dependency, but then again I know nothing about the inner
workings of the XFS code.
I'm now hoping that you have an idea what's going on here.
Thanks, Jan
