Title: AER PCIe Bus Error for Asus X541UVK Status in linux package in Ubuntu: Incomplete Bug description: I already posted this on the Ubuntu Forums and I'm revisiting it now with more information and accuracy. 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.
