Couldn't find mci handler

Panic on boot. I don’t know what an “MCI” is and I don’t know if the handler is a missing driver or some broken hardware.

(I’d surely like to understand why I cannot upload a jpeg image directly. This is too round-about. I had to parse a flickr page source to get the jpg URL.)

Your panic has nothing to do with MCI handler.

That thread starts by asserting that the kernel firmware is the culprit.
How do I determine that that is my issue?
The affected system does not have Bluetooth, so I doubt I’ll be able to turn it off.

That was a kernel and kernel-firmware bug on the ath10k_pci, which is also build in your PC…

Thank you. Confirmed.

Being as how I don’t actually use the wi-fi stuff on the motherboard, can I just disable the blasted thing instead of trying to replace the firmware? (Partly because I’d like to avoid crawling around behind my desk to plug in another keyboard. It is quite difficult. The mobo firmware can use my two-system-switched keyboard and so can the full install, but not the “rescue” kernel.)

Do you really think it’s the WiFi device and not the system memory?

Recommend…
If this is a new machine, run memory check or replace memory if replacement available (or replace the first slot memory).
If you don’t have spare memory, try cleaning the memory leads by

  • Pulling the memory (specifically the first slot which is what the error is complaining about)
  • Use a pencil eraser to gently rub the exposed electrical contacts.
  • Replace the memory, carefully being sure the memory is seated properly.

There’s no use for this post. @Sauerland identified the issue, which is known and a fix on the way for.

Try booting with modprobe.blacklist=ath10k_pci on kernel command line. If it works, install latest kernel update.

Worked like a charm. I added it to /etc/modprobe.d/50-blacklist.conf. I’ll figure out the update later.
