I don't think the NVME drive is behind VMD on the HP machine I am
observing the issue, so I don't think the VMD patches and issue are

Hi @kaihengfeng,
Any idea how I can test this patch?
My understanding is that the commit it fixes: f492edb40b54 ("PCI: vmd:
Add quirk to configure PCIe ASPM and LTR") was added in v6.3 and yet the
6.5 Ubuntu series was working fine on the machine.

Looks like it's the NVMe device doesn't set the ASPM state correctly.
Could you try the latest proposed kernel 6.8.0-40 which included one ASPM
related fix that might help.
Thanks.
