You'll find them attached, but I got a strange error when I wanted to
run it as root:
$ sudo lspci -vv > lspci_vv_before
pcilib: sysfs_read_vpd: read failed: Connection timed out
$ sudo -i
# lspci -vv
pcilib: sysfs_read_vpd: read failed: Connection timed out

So I only got the unpriviledge output.

Some complementary lines from my journal:

kernel: r8169 0000:03:00.2: can't disable ASPM; OS doesn't have ASPM control

And one I thought of interest:

kernel: rtsx_pci 0000:03:00.0: vpd r/w failed.  This is likely a
firmware bug on this device.  Contact the card vendor for a firmware update.

That came three times before suspend.

Only two lines about hotplug, none special.

Stripped journal attached for the suspend cycle.

Sorry, I didn't mean to underestimate the amount of work you put in that
bug resolution (actually it was the first time I heard of kernel
bisection and was pretty impressed by how you led it).
What made me say it had been a fast resolution is that its fix was
included right in the next kernel revision, which I found to be quite
diligent. But the actual work to find it, the kernel bisection, that
must have been a real sweat.


Thanks
