Testing on my other machine (already on f32) did not show the above messages.
However, being a 2009 vintage, makes the hware less sophisticated, and maybe the newer hware
is too smart for its own good?

10+ years is enough to find and fix all the bugs, especially if you were lucky enough to catch
the first use of a chip that became popular.   OTOH, if you happen to catch the last machine 
that used a problematic chipset, new kernels may not even have the drivers.   Also, if you 
have a problem running linux on older hardware, there will be discussions of the issue.  A
search for the problem with the make and model of the PC and USB ID of the prime suspect
often provides useful information and may tell you which kernel version has the fix.

Agreed, my sentiment as well.

Still, as this is repeatable, I wonder if running a debug kernel (kernel-debug) will reveal more?

Google may tell you someone else has already done the heavy lifting, and which kernel has the
fix.
