GameCrashes PCIe Bus Error

Support and Help
1

Hello i use the Ubuntu Support Template and i hope my english is enough.

Ubuntu Version:
24.04

Desktop Environment (if applicable):
GNOME

Problem Description:
Got a few crashes in a Game (BG3) per Session, what workd for months perfect.
I do not think its BG3 cause there wasnt a big update lately.

Normaly i try a mix out of google and gpt searchin
but can`t re-google trough gpts examples.

After doing with google an BIOS Update the crashes still happend.
so searchd with gpt.

GPT told me usin this
”sudo dmesg | tail -50 journalctl -b -p err --no-pager | tail -100 free -h nvidia-smi” ←i have the full outcome if needed

And that this is the Problem
”nvidia 0000:01:00.0: PCIe Bus Error
type=Data Link Layer
[6] BadTLP”
With repeating
”timeout”

The solution from Gpt is
changing this
”GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash””
to this
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pcie_aspm=off pci=noaer”

I try to re-google GPTS answer but cant come to the exactly same use cases.
What made me suspicios and bring me here.

Is this good try?
or should i do something diffrent?
and Is the crash report command good?

Hope my english is good enough,
criticism welcomed.

Thanks for your help.

Before editing the GRUB file permanently, you can test those parameters first. At the GRUB menu on boot, press E to edit the entry. Find the line with quiet splash and add this to the end of it:

pcie_aspm=off pci=noaer

Press Ctrl+X to boot. It’s not permanent — it resets on next reboot. Play BG3 long enough to normally trigger a crash and see if it holds up. If it does, then make the GRUB edit permanent.

Thank You
I will try it.

Also in after a try to change the Driver.
I made this
”dmesg | grep -i pcie”
and
i got warnd that this output
”limited by 2.5 GT/s PCIe x8 link”
could mean a hardware error
Is that right?

Little feard the Laptop is only 8Months old

I changed it to only ”pcie_aspm=off”
cause if i not miss read it is ”pci=noaer”
to turn of special reports.

So i only used,
”pcie_aspm=off”.

Checked after booting
with = sudo dmesg -w | grep -i pcie
outcome = no pcie errors

and checked in/after the game
also no pcie erros.

Also no Crash in this Session.

I will Check this Topic in a Week as Solution.

Thanks Rawrmonster to pointout the not Permanent change option!
