This is truncated on top, and so less useful than it otherwise would.
And it's truncated because of this:

You built a kernel with some silly debugging, which made the dmesg
to explode.

This tells us enough (without any debugging options), your interrupt
routing is busted.

We know that this is not the Wedgewood's "VIA cleanup", because
in your case the quirk was applied. But since the diff was truncated,
there's no telling. Observe that that ALSA stuff you load out-of-tree
shares IRQ 11 with the failing EHCI, for example.
