Manjaro/Arch: Disabling IRQ #31 (Thinkpad X1 7th)

Question

I've stumbled upon the beforementioned error (disabling IRQ #31) during boot and have tried to resolve it by trying to find out what caused the interrupt. Running lspci -v | grep 31 lspci -v | grep 31 gives no result and a cat /proc/interrupts | grep 31 cat /proc/interrupts | grep 31 returns:

  31:          0          0          0          0     100000          0          0          0   IO-APIC   31-fasteoi   tpm0

How should I proceed knowing that it maybe has to do something with IO-APIC 31-fasteoi tpm0 ?

Many thanks.

I ran into a similar problem on my Lenovo L390 (running Fedora 31). In my case the issue reproduced by waking up the laptop when in suspension mode.

For me the issue was resolved (or worked around) by disabling the Trusted Platform Module in the BIOS.
