Hi folks,

setup:
	kernel 5.18.14 (built from git)
	Qnap TS-559 Pro II, 4*3.5 HDD + 1 SSD, /boot is on USB stick
	Intel(R) Atom(TM) CPU D525
	Debian Sid

On a reboot after some runtime my Qnap TS-559 Pro II shuts down cleanly, but
after the kernel and initrd are loaded again it writes an endless stream of
messages to the console

pcieport 0000:00:1c:0: pciehp: Slot(0): Card present

Appr. 2 lines per second. I get an emergency console to login, but it
is garbled.

If I wait a few minutes to let the qnap cool down it boots again.

[...]

Is this a regression?  Was it also present on older kernel versions?

The PCIe Root Port 0000:00:1c:0 is hotplug-capable and is constantly
signaling an interrupt.  Upon checking the Slot Status register,
the PCIe hotplug driver discovers that the Presence Detect bit is set,
i.e. the hardware signals hotplug of a card.  However when trying
to bring up the slot, the link fails to go up.

What's the Secondary Bus number of that Root Port?  Is there a PCIe
device below it or is the Presence Detect bit just a phantom?

If you open a bug at bugzilla.kernel.org and attach full dmesg and
lspci -vvv output plus an ACPI dump, we can analyze the issue further,
but I suspect this is a BIOS issue (vendor probably forgot to disable
that Root Port) and you need to ask your vendor for a BIOS update.
It doesn't look like a bug in the kernel to me at first glance.
If your vendor is unresponsive, you can try removing the offending
Root Port via sysfs on boot.

Thanks,

Lukas

Hi folks,

sorry for the double post. Please ignore.

Hi folks,

setup:
	kernel 5.18.14 (built from git)
	Qnap TS-559 Pro II, 4*3.5 HDD + 1 SSD, /boot is on USB stick
	Intel(R) Atom(TM) CPU D525
	Debian Sid

On a reboot after some runtime my Qnap TS-559 Pro II shuts down cleanly, but
after the kernel and initrd are loaded again it writes an endless stream of
messages to the console

Appr. 2 lines per second. I get an emergency console to login, but it
is garbled.

If I wait a few minutes to let the qnap cool down it boots again.

Try posting on the linux-pci@vger.kernel.org list, that is the best for
this type of thing.

Hi folks,

setup:
	kernel 5.18.14 (built from git)
	Qnap TS-559 Pro II, 4*3.5 HDD + 1 SSD, /boot is on USB stick
	Intel(R) Atom(TM) CPU D525
	Debian Sid

On a reboot after some runtime my Qnap TS-559 Pro II shuts down cleanly, but
after the kernel and initrd are loaded again it writes an endless stream of
messages to the console

Appr. 2 lines per second. I get an emergency console to login, but it
is garbled.

If I wait a few minutes to let the qnap cool down it boots again.
