This is a relatively known issue. I see it on my Talos II (regular,
currently single-CPU). It only affects performance, it doesn't affect
system stability, in my case anyway. Some others have reported NVMe
crashes, but I haven't reproduced on my hardware. We haven't yet
determined the cause of the missing interrupt, but it happens often,
and causes things to hang for a bit before continuing.
We still have a bit of work to do on the stability and performance
sides on POWER, particularly with the interrupt controller (XIVE) and
the PCIe controller.
