sysctl -p failed on /proc/sys/pcie_aspm

As revealed in the comments, there’s a

pcie_aspm=off

line in one of the files which sysctl -p reads. This causes sysctl to attempt to write to /proc/sys/pcie_aspm; if that doesn’t exist (and it won’t, it’s not a valid sysctl entry, it’s a kernel boot parameter), you’ll get the error shown in your question.


The parameter may be not supported by the kernel due to the inexistence of PciExpress subsytem.

Or it can be also the pcie_aspm is disabled.
