Kernel 6.12.35 freeze

I'm annoyed, because so much to do developing the new Easy Exaclibur; this kernel freeze is a major distraction. Yesterday, as got the devx sfs working, thought might as well compile the latest 6.12.x kernel.

Then recalled reading something at the Gentoo wiki, here:

https://wiki.gentoo.org/wiki/USB/Guide

Device Drivers  --->
    [*] PCI support  --->
        [*] PCI Express Port Bus support
        [*]   PCI Express Hotplug driver
        [*] Support for PCI Hotplug  --->
            [*] ACPI PCI Hotplug driver

The kernel that I have been using, 6.12.32, has this:

Device Drivers  --->
    [*] PCI support  --->
        [*] PCI Express Port Bus support
        [ ]   PCI Express Hotplug driver
        [*] Support for PCI Hotplug  --->
            [ ] ACPI PCI Hotplug driver

Alright, so followed Gentoo's advice and ticked those two boxes.

It boots, then a moment after the GPU driver module loads, everything freezes, requires holding down the power button to turn off. At first thought it might be the Intel i915 GPU driver, so booted with "nomodeset" kernel parameter. Freezes in the same place. Tried a few other things, no go.

So, the problem is either enabling those two boxes, or there has been a kernel regression.

Note, Gentoo also recommends this:

Device Drivers --->
    [*] Unified support for USB4 and Thunderbolt

...which I did not do. Tried that about a year ago, and the 'blkid' utility in the initrd didn't work.

So, I suppose do another kernel compile, with those two disabled.
