Yeah, this was just an early heads up.

It uses multiple vectors, but now it falls back to trying to allocate a
single one and even that fails with -ENOSPC:

	ath11k_pci 0006:01:00.0: ath11k_pci_alloc_msi - requesting one vector failed: -28

Similar for the NVMe, it uses multiple vectors normally, but now only
the AER interrupts appears to be allocated for each controller and there
is a GICv3 interrupt for the NVMe:

Next boot, after disabling PCIe controller async probing, it's an MSI-X?!:

201:          0          0          0          0          0          0          0          0  ITS-PCI-MSI-0006:00:00.0   0 Edge      PCIe PME, aerdrv

205:          0          0          0          0          0          0          0          0  ITS-PCI-MSI-0002:00:00.0   0 Edge      PCIe PME, aerdrv
206:          0          0          0          0          0          0          0          0  ITS-PCI-MSIX-0002:01:00.0   0 Edge      nvme0q0

This time ath11k vector allocation succeeded, but the driver times out
eventually:

See below (with synchronous probing of the pcie controllers).
