ppb4 at pci4 dev 0 function 0 vendor "Intel", unknown product 0x15c0 rev 0x01: not configured by system firmware
I dunno if this is helpful, but I just unplugged my thinkpad and triggered the behavior.

ACPI shot right up, and in this case the "charging" LED has stayed on. I've never triggered
it by unplugging before, but the symptoms are the same. The system was under some load while
doing so (watching a video in Firefox and extracting a backup.) The last line in dmesg also
seems weird to me; it might be a firmware thing, from that.
