Hi Vinicius,

thanks a lot - that patch fixed it! Both "normal" shutdown as well as
ifdown/ifup are working without issues now if CONFIG_PCIE_PTM is
enabled in the kernel config.

I've done a DSL download/upload speed comparison against my current
5.14.0-19.2 and did not see any performance differences outside margin
of error. I currently have no other Linux machine I could use for iperf
but I will report if I encounter any issues.

As I am not familiar with the kernel development procedure: can you
give a rough estimate when we may expect this patch in the stable
branch?


Thanks again,
Stefan
