I have the following error in PCIe bus since I installed kernel 5.4;

Also read in redhat bugzilla that setting pcie_aspm=off could get rid of this kind of errors:
https://bugzilla.redhat.com/show_bug.cgi?id=1616364

What would you suggests me to do?

Thanks

----------------

Seems that kernel 5.4 is more verbose than 4, since I never saw this error before.

I didn't notice any performance issue around IO.

My concern was if this issue could be hardware or software related. As I could see from redhat bugzilla, someone could disable this errors configuring pcie_aspm=off, so could be related to power management.

----------------

Could be related to my graphic card gtx 1060:

Here they suggests pci=nommconf to stabilize the cpu.
----------------

After adding pcie_aspm=off to grub in kernel boot parameters, system boot little faster and don't see until now the error happening again.

Some users run a canned search for threads with zero replies as a way of finding posts to answer. When you replied to yourself, you removed your thread from that list, even though you were not replying to announce that the thread was solved. Thus, they would no longer see your thread on the list of unanswered threads.
