error on loading ahci - possibly related PCIe issue

I suspect this might be a general PCIe issue instead of just nvme.

I setup a system with a SATA SSD via a PCIe controller card (JMicron JMB545
based) and it failed to boot as well.

Booting from USB I was able to blacklist nvme and ahci, and then obtain a
crashdump when nvme was modprobe'd after boot.

The NVMe crashdump has been uploaded to:
ftp://support-ftp.us.suse.com/incoming/bug-1187701-ten64-nvme-crash.tar

modprobe of ahci did not cause a kernel crash but the call trace has been
attached.

I also have an ath10k_pci wireless card (QCA6174) in this system and 'modprobe
ath10k_pci' simply stalls with no error messages. So a general PCIe issue is
quite likely here.
