Public bug reported:
Hi Ubuntu,
We have found that when we boot up the system, Dmesg would show BAR13 failed to
assign error. (Refer to the attached file)
We tried to modify the IO size in BIOS code to fix this issue, but we occurred
system hang issue when we enlarged the IO size.
We have found that there're two same issue in Bug #1426216 and Bug #1986792.
It seems that this issue has existed in different platform for a long time.
But we don't see the conclusion about this issue.
We would like to know will this error message impact the system?
Or this this just kernel bug?
Our Ubuntu version is 22.04.
Kernel: 5.15.0-125-generic
