Problem with modules in 4.10.6-1? [Solved]

I upgraded my kernel on a server from 4.10.4-1 to 4.10.6-1, and suddenly I lost all of my network interfaces, as well as other devices.  Basically systemd-modules-load.service totally failed and the machine was unusable.  I reinstalled the kernel, just in case, but no improvement.  Downgrading to 4.10.4 fixed the problem.

Here's the sha256sum of the kernel package I tried:

639f0ce57ff2621d944c1e3e4c9084d8abddcb608dd85e7f7acd7d44056e7259  /var/cache/pacman/pkg/linux-4.10.6-1-x86_64.pkg.tar.xz

Has anyone else experienced similar issues?

Yup, had the same issue going from 4.10.5 to 4.10.6 and downgrading did the trick.

Your best bet is to bisect the kernel and report the commit that breaks things in the upstream bug tracker.

Run lsmod under 4.10.4 and redirect to a text file.  Do the same under 4.10.6.  Sort each list them diff them.  Are there any differences?  In other words, did a module or more than one not get loaded?  That can help you narrow it down if the fit bisect is too much for you.

Does the journal output from a 4.10.6 boot for systemd-modules-load.service not contain the names of modules that fail to load?

As a sanity check, did you run uname -a with the new kernel installed?  Did the reported version match that of the installed version?

Checking to see if your boot loader managed to pick up an old kernel for which there are no longer drivers installed.

Unfortunately, it doesn't print this out, and journalctl is not useful because somehow it resets all the logs after booting.  But the problem is obviously modules failing to load.

So I just upgraded again to investigate further, and this time everything was fine.  I can't reproduce the problem any more, even though the sha256 hash of my kernel file has not changed.  I'm not sure what else changed, but before I did try reinstalling my kernel to no avail.
