There's me for ibm-acpi-devel, but let's make one thing VERY clear:
1. I do not work for Lenovo or IBM, I never did. I am a volunteer.
2. That specific ML is about the thinkpad-acpi driver, not about anything
else, not even generic ACPI issues.
Also, I work on thinkpad-acpi on my spare time, I do not have the hardware
to test many of the issues in the first place as I get no help at all from
Lenovo Brazil, so my resources to help are often very limited.

This is not a thinkpad-acpi bug as far as I can see, but thinkpad-acpi is a
completely optional driver: anytime you suspect it of something, you just
remove it, reboot, and check if things start working. If they do, you can
contact me about it and we will find the root cause and fix it.
On a related note, for a while you *could* unofficially reach some Lenovo
people through the linux-thinkpad ML. You'd comment on something there --
with **all** the relevant detais as you often would get only one shot at
getting their attention, so you must make it count! -- and after a while,
Lenovo would (often silently) act on it. I am unsure if they are still
lurking there, but you could try.
That said, please ensure you're running the latest Lenovo firmware on *any*
ThinkPad that is experiencing issues, and install your distro's distribution
for the Intel processor package unified update (aka "Intel microcode update"
-- it was reported that nowadays it updates more areas of the chip, such as
power management control/tables, etc.).

Same deal as bugzilla #100171, above.
