I run with `pcie_aspm=force pcie_aspm.policy=powersave` on my > command line. But I wasn't seeing these messages in 5.8. I'm sorry that you need to use "pcie_aspm=force pcie_aspm.policy=powersave". Someday maybe we'll get enough of ASPM fixed so we won't need junk like that. I don't think we're there yet. Do you build with CONFIG_PCIEASPM_POWERSAVE=y? Do you need "pcie_aspm=force" because the firmware tells us not to use ASPM? Re: the messages below, they come from Link Bandwidth Management interrupts. These *should* only happen because of a software-initiated link retrain or because hardware changed the link speed or width because the link was unreliable. ASPM shouldn't cause these. So it's possible you have an unreliable slot, but I doubt it because you said v5.8 works fine, and also the Link Bandwidth interrupts should only happen if something *changed*, but all the messages below look the same to me. Something is also wrong with them -- there's no such thing as a "x63" link. But maybe these are copy/paste errors? I don't know where the "b.4" comes from either. Oh, that probably belongs with "0000:00:1b.4" but got separated by copy/paste. Obviously you can stop the messages by unsetting CONFIG_PCIE_BW. The code (drivers/pci/pcie/bw_notification.c) is pretty straightforward and I don't see an obvious problem, but maybe Alex will. > [79960.801929] pcieport 0000:04:00.0: 31.504 Gb/s available PCIe >
