This device is very old and actually already EOL, so I'll not be able to get any support
for this internally. D3 works fine with this NIC on standard, off the shelf laptops,
so I'd guess that the probem could be rooted in the tablets' PCIe hardware or maybe the
BIOS itself.

D3cold support has been a problem area, and there are some changes in
progress [1] that could be related.
Could you possibly collect the complete dmesg logs (with a recent
upstream kernel, e.g., v6.4, if possible)? And the output of
"sudo lspci -vv"? And the contents of /sys/firmware/acpi/tables/?
You can attach them to the Debian bug report if that's convenient for
you.

Yeah; no harm in at least trying this series. I'd love another data
point with it.

Yes this could be related but it will come down to
1) Whether the root ports are considered power manageable.
2) The system uses S0ix or not.
whether the series could help as it stands today.
Please CC me into any kernel bugzilla that you open against a mainline
or stable kernel and can capture the lspci output, the dmesg and
acpidump and I'll look at it.

BTW - Bjorn, can I have comments on the last patch in this series? I
have fixes ready locally for everything in the earlier patches that Andy
gave feedback but I was hoping for some feedback on the very last patch
before I sent out a v12.
Thanks!
