Frederick reports:
I recently purchased a Thunderbolt 4 dock (CalDigit TS4) and started
having millions of these warnings in my logs after resuming from sleep.
I previously didn't have any Thunderbolt peripherals. The device is a
ThinkPad X1 Extreme Gen 5 (BIOS 1.12 N3JET28W, EC 1.08 N3JHT21W).

And disabling ASPM seems to have some effect:
It happened every time after resuming from sleep. pcie_aspm=off solved
the issue for me.
But also broke other stuff:
I just realised that pcie_aspm=off broke most of my dock's functions. I
still had Ethernet but wake-on-lan stopped working. The dock's
Thunderbolt ports, USB Type-A/C data ports, SD card slots all stopped
working too (no logs at all after plugging in things).
Then I tested pcie_aspm.policy=performance. The dock started working
again but the warning logs were also back.
Also tried applying quirk_disable_aspm_l0s_l1 on the Thunderbolt bridges
but unfortunately I still had the logs.
