The above comment might not be correct, because it turned out one of the
micron nvme devices had a defect and was not recognized by any hardware
at all, even when not hot swapping.
There is a chance that this is related to the bios/firmware combination
on this supermicro model.
I will test this a
I was finally able to test this with the mainline kernel:
6.1.10-060110-generic #202302060840
taken from: https://kernel.ubuntu.com/~kernel-
ppa/mainline/v6.1.10/amd64/linux-image-
unsigned-6.1.10-060110-generic_6.1.10-060110.202302060840_amd64.deb
and it works!
this is specific about hot swap.
okay, it seems that both acpi_pci_hotplug and pci_hotplug are enabled
for this kernel:
grep "CONFIG_HOTPLUG_PCI_ACPI=" /boot/config-`uname -r`
CONFIG_HOTPLUG_PCI_ACPI=y
grep "CONFIG_HOTPLUG_PCI=" /boot/config-`uname -r`
CONFIG_HOTPLUG_PCI=y
but still, hotplug is not working.
the current situatio
as already stated above I did provide log files manually, as apport-
collect is not installed on this system.
I'm happy to provide further logfiles to debug this issue.

my vendor told me this should work with updated bios and firmware, which
it does not.
in fact, I can't even find the pci hotplug kernel module, neither
loaded, nor present under /lib/modules/*.
so could you please reopen, so we can double check I'm not missing
anything from the ubuntu side?

Our vendor told us that this is a generic problem with the following
supermicro board/system and many nvme ssd devices:
Board: H12SSW-NT
Servertype: Supermicro AS -1114S-WTRT

I wasn't able to test this just yet as I have limited time for debugging
this and it is a production system, so I need to prepare maintenance
etc. so it might take some time.
Do you have any information if this is supposed to work on this kernel?
I saw some patches afaik from 2017~2019 which addr
so, we seem to have a dependency problem here, no?
for reference, this is fixed by:
apt install linux-tools-common
but why was "linux-tools-common" not installed as a part of "linux-
tools-generic-hwe-18.04"?
this is the dependency chain:
