The PCIe Bandwidth Change Notification feature logs messages when the link bandwidth changes. Some users have reported that these messages occur often enough to significantly reduce NVMe performance. GPUs also seem to generate these messages. We don't know why the link bandwidth changes, but in the reported cases there's no indication that it's caused by hardware failures. Remove the bandwidth change notifications for now. Hopefully we can add this back when we have a better understanding of why this happens and how we can make the messages useful instead of overwhelming.
