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. - Justin
