The dmesg logs from your initial report:

  pcieport 0000:04:00.0: 31.504 Gb/s available PCIe bandwidth, limited by 8.0 GT/s PCIe x4 link at 0000:00:1b.4 (capable of 1984.941 Gb/s with 32.0 GT/s PCIe x63 link)

are almost certainly seeing ~0 responses to config reads of 04:00.0.
That would happen if 04:00.0 were powered off or if the bridge leading
to it (00:1b.4) were in Downstream Port Containment mode.  00:1b.4
does support DPC, but none of the lspci logs you attached show DPC
being triggered.  If it were, you should see some indication in dmesg
as well, e.g., the "containment event, status:%#06x source:%#06x\n"
message from dpc_process_error().

If you can collect the complete dmesg log, especially after you get
the bandwidth notification spam, it might have a clue.

Just to re-confirm: this happens with v5.8 but not with v5.9?  (v5.9
had not been released at your initial report, so I assume you meant
v5.9-rc8 or something?)

If you can bisect, that would be the easiest way to identify the
problem.

You know, more errors today make me suspect that maybe the thunderbolt
controller in my laptop is just dying. I'll go back to 5.8 for a few
days and see if the problem disappears. If it doesn't, we'll chalk
this up to a hardware failure.

Right, I think you and Keith nailed it: likely we read ~0 from
PCI_EXP_LNKSTA because of some error.  I don't know what the
connection with ASPM would be, although we do have some known problems
with ASPM configuration, especially in "powersave" mode; see [1]

Jason, could you capture the "sudo lspci -vvxxx" output and dmesg log
after the messages start?  You could instrument bw_notification.c so
it shuts up after a few messages if necessary.  The lspci should show
us if a port leading to the device is in DPC or other error condition.

DPC takes down the link (as would an AER event).  It doesn't seem like
these should cause Link Bandwidth Management interrupts, but maybe?

Hi Bjorn,

That log looks like the PCIe registers spitting wrong values, but all I 
can do is speculate. Have we verified we don't have a race condition 
between ASPM and pcie_report_downtraining()?

I wouldn't be surprised if the cause of the messages is the device (or 
downstream port) faking all f's responses. I don't see how else we'd get 
links reported as x63 32GT/s.

Alex

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.

A x63 gen5 capable link?! No such encoding exists, so something is
definitely wrong. Looks like all 1's was returned when reading the link
capabilities register, as that equals the mask's 0x3f value. The code
ought to skip reporting a device returning all 1's.

Hi,

Since 5.9 I've been seeing lots of the below in my logs. I'm wondering
if this is a case of "ASPM finally working properly," or if I'm
actually running into aberrant behavior that I should look into
further. I run with `pcie_aspm=force pcie_aspm.policy=powersave` on my
command line. But I wasn't seeing these messages in 5.8.

Jason
