So the patches indeed helped resolving the deadlock but when we try

and more detailed bellow,
we are trying to debug but again, you might have a quick insight
Well, the link doesn't come up. Is the Link Disable bit in the
Link Control Register set for some reason? Perhaps some ACPI method
fiddled with it?
Compare the output of lspci -vv before and after the system sleep
transition, do you see anything suspicious?
If you reset the slot via sysfs, does the link come back up?
You may want to open a bug over at bugzilla.kernel.org and attach
the full dmesg output which didn't reach the list, as well as lspci
output.
We will follow on all your advises and update you
Did you apply only my deadlock fix or also Kai-Heng Feng's AER disablement
patch?
Yes we did.

Thanks,
