Kernel Error IRQ

[Pablo Catalina]

Lenovo p52 with Thunderbolt dock (2 HDMIs - one connected, few USBs 3.0 - one with an external HD connected, and one USB-C)

I noted that the mouse and keyboard using one Logitech Unifying receiver (connected through USB on the Laptop, not dock) started to jump over the screen and responded bad. I noted on dmesg the following error:

NOTES: Ubuntu Focal just installed, enabled the thunderbolt and allow it (I had to poweroff the laptop, otherwise the External displays connected to the Thunderbolt did not work)

NOTE: The mouse is still making jumps and does not respond when I perform a file transfer from the Dock USB external drive (big files that take long to copy).

I think i801_isr needs to be marked with IRQF_NO_THREAD. Please try this kernel and see if it fixes the problem: https://kernel.ubuntu.com/~sultan/i801-lp1873673/

[post-factum (post-factum)]

So, Pablo, does this work?
