Probably you need to hack BIOS code to keep monitoring clkreq# as an

ASPM issues come with quite different symptoms. Sometimes there's just a
number of rx_missed errors and performance is significantly reduced, w/o
tx timeout. Therefore at least in mainline I'd like to keep ASPM
disabled per default. But every user or distro can use sysfs to enable
selected ASPM
Is it possible to defaults to ASPM enabled, and disable ASPM in

Well, reason could by anything. Most users of this chip version don't

OK, I just did the following (all on 5.4.0-33-generic):
* modified /etc/default/grub to include " pcie_aspm=off" in the kernel command
line
* `update-grub`
* `reboot`
* double-checked that "pcie_aspm=off" was in the kernel command line, then
booted
* once booted and logged in, I disabled
I'll try the command line change after my morning meetings; here's the
requested debug output:
