>>>
>>> How I tracked down the problem commits:
>>>
>>> I was not able to successfully "git bisect" this bug - I seemed to run
>>> into a mess of unrelated problems/errors that sent me down a rabbit hole
>>> chasing who knows what. I had already manually narrowed down the bug to
>>> amd_sfh by blacklisting modules, so I reverted each
>>> drivers/hid/amd-sfh-hid commit on the stable linux-6.9.y branch (v6.9.8
>>> known "bad"), back to v6.6 (known "good"), and then manually bisected
>>> the revert commits, landing on "HID: amd_sfh: Improve boot time when SFH
>>> is available" (2105e8e00da4) as the first "bad" commit.
>>>
>>> I wanted to be able to test with only the "bad" commit(s) removed; it
>>> turns out 6296562f30b1 ("HID: amd_sfh: Extend MP2 register access to
>>> SFH") needs to be reverted to do that. Everything seems fine with these
>>> two commits reverted (again, this in on the stable linux-6.9.y branch).
>>>
>>> When testing, "bad" commits usually quickly display some variation of
>>> the page dump/BTRFS errors, similar to the dmesg output below. I
>>> consider commits "good" if the system survives "stress-ng --all 2
>>> --vm-bytes 50% --minimize --syslog --status 10 -t 5m" (run as a non-root
>>> user), which was usually followed by building the next test kernel. The
>>> "bad" commits often show errors before I even get to the stress test.
