Hi Thomas,
The following commit causes the out-of-tree mwlwifi driver [1] to crash,
which
I have found with git bisect.
commit 1f08673eef1236f7d02d93fcf596bb8531ef0d12
Author: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
Date: Thu Oct 18 17:37:18 2018 +0200
PCI: mvebu: Convert to PCI emulated bridge config space
Convert the pci-mvebu driver to use the pci-bridge-emul logic, that
helps emulating a root port PCI bridge configuration space.

I have raised the issue with the driver maintainers but they responded
that
this is a kernel regression [2].
Do you think this is a driver issue or a regression? I am happy to test
proposed
fixes but I don't understand enough about the driver or PCI to
investigate.
If I revert that single commit, the issue goes away.
Any help would be gratefully received.
The crash dump is as follows:

I believe the issue comes from the fact that your PCIe device has prefetchable BARs, while none of the 5 PCIe devices I have here has prefetchable BARs. The pci-mvebu driver doesn't support such BARs, but the change to the common PCI bridge emulation logic made the prefetchable memory base / limit register read-write while they were read-only before.
