Opt-in Linux 6.2 Kernel for Proxmox VE 7.x available

[james58899]

PCI passthrough of some USB controllers got broken after 6.2.6.

I'm passing through two of my motherboard's USB Extensible Host Controller (same IOMMU group) to a Win 11 VM and I noticed one of them failed to initialize on Windows after a kernel update.

I tried a fresh Win installation to rule out any Window config issue. Same problem.
I tried an Ubuntu VM where it also used to work. Same problem.

It's broken on 6.2.9-1, 6.2.11-1 and 6.2.11-2.
It works correctly on 6.2.6-1 and 5.19.17-2.

So this seems to be related to any change between kernel version > 6.2.6 <= 6.2.9

I have the same problem on my x570 motherboard.
Solved by setting disable_idle_d3=1 on vfio-pci.

I had the issue again and this time I fixed it by making sure the device was unbound from the xhci_hcd driver using a hookscript.
