All right, I tried to do some more digging around, in the hope of
getting as close to the source of the problem as I can.
I went back to the very first commit that went astray for me, 2db1f95
(which is the only one actually panicking), and tried to move from its
parent 90ad9e2 (that boots fine) to

Attached, but heads up on this: when redirecting the output of lspci
-vvv to a text file as root I get
pcilib: sysfs_read_vpd: read failed: Input/output error
I can find bugs filed for various distros to this same effect, but
haven't tracked down any explanations.

Good enough. Thanks !
Attached.
I don't have a 4.14 family kernel available at the moment on that
machine. What I'm attaching comes from the 4.13 one I was playing with
yesterday, what with kexec and all.

No; it seems to be tied to this specific issue, and I was seeing even
before getting logs just now, whenever I'd start one of the bad
kernels in recovery mode.
But no, I've never seen that in any other logs, or on any other
screens outside of those popping up in relation to this problem.

I was just now trying to track down my other issue, whereby somewhere
along the tree kexec stops working properly. In the process of doing
that I realized I had initially made one change to the original 4.9
config beyond oldconfig: I'd turned off WX debugging.
I've now compiled a bunch of versions
