Hi, I currently do not have access to a running linux system to compile and test the patch with, since the only pc that I have is my laptop affected by this bug, and I also really need windows on it for some windows-specific software for my university. So, It's not possible for me right now to test the patch. I'll leave some more specific info about my system (hoping that somebody else has the same exact machine) for anyone that is willing to test this (I'm copying this from System Information).
System Model X541UVK Processor Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz Adapter Description Intel(R) HD Graphics 620 Adapter Description NVIDIA GeForce 920MX BIOS Version/Date American Megatrends Inc. X541UVK.308, 30-Jan-18 Thanks to everyone for the help, I'll keep in touch.

Whenever I try to install any flavor of *buntu, I always run into this problem; a process taking up all of my CPU and after a while, it crashes the system and the whole screen goes black with text spamming. It shows some PCI errors non-stop, and following some guides online i tried to fix it but never actually succeeded. The distro I was trying to install this time was the default 20.04.2 Ubuntu. My PC is a laptop, it's an ASUS X541UVK with an i7 7500U and Geforce 920MX. At first I thought that there was a problem with the Nvidia GPU but it appears to be with the Realtek BT card. I went to follow this guide: https://forums.linuxmint.com/viewtopic.php?t=305970 (since using pci=nomsi once solved the issue some time ago) And the reproduced steps from the guide above are here (from the live usb): https://imgur.com/a/enq5UCt However this still doesn't solve my problems. I submitted my information at the time on this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1521173 But now I made a duplicate of the bug since my pc has slightly different hardware. Also, I have a little bit more free time now. So, this time, I tried again with Ubuntu 20.04.3 and the results were pretty much the same; after booting up Ubuntu reported an "internal error" and I just managed to open the Gnome System Monitor (and sort the processes by CPU usage) just before the entire pc froze. Here are some pictures: https://imgur.com/a/Sd7TO4y Then, as suggested in the original bug report ( https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1521173/comments/139 ), I tried booting using the "pci=noaer" option, and the desktop at first booted fine, much quicker than before also, but for a few seconds the screen went black and these appeared on screen: https://imgur.com/a/Ppq2D0W Then after that it just went back to normal, and I didn't notice any anomaly. Also here (again, as suggested in the other bug report) I copy-pasted the results of "lspci -nn" and "dmesg": https://pastebin.com/HMvdhvnz https://pastebin.com/pnjPNcWr I really hope this helps towards finding the issue :) for anything else for me to try, feel free to suggest and I'll try it and report the results.
