I reproduced the problem with 6.2-rc1 in a Fedora 37 installation with
early kdump enabled as described at
https://fedoraproject.org/wiki/How_to_use_kdump_to_debug_kernel_crashes
https://github.com/k-hagio/fedora-kexec-tools/blob/master/early-kdump-howto.txt
I panicked the kernel with sysrq+alt+c. The dmesg saved with kdump
showed warnings at drivers/pci/ats.c:251 pci_disable_pri+0x75/0x80 and
at drivers/pci/ats.c:419 pci_disable_pasid+0x45/0x50 involving AMD IOMMU
and amdgpu functions in the trace. Since those warnings' were
if (WARN_ON(!pdev->pri_enabled)) and if (WARN_ON(!pdev->pasid_enabled)),
pci_disable_pri and pci_disable_pasid looked like they were called when
pdev->pri_enabled and pdev->pasid_enabled were both false. A null
pointer dereference occurred right after that which made amdgpu crash.
