Maybe there is a better fix for this issue.

Comment 12 limanyi@uniontech.com 2022-07-14 11:09:41 UTC 
Passing pcie_aspm=off to the kernel command line solves this problem.
Comment 13 limanyi@uniontech.com 2022-07-15 05:24:50 UTC 
the kernel command line does not have "pcie_aspm=off", lspci -nnvvk is
