We had tested Fintek F81504/508/512 PCIe-to-UART/GPIO on Intel Skylake platform. It's maybe flood AER correctable error interrupt and slow down the system boot. It's the same issue about below link: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1521173 and this IC will malfunctional after suspend/resume (S3, D0->D3->D0) on Skylake platform. The first patch will use parent AER interrupt mask to prevent generating correctable error interrupt, the and second will prevent the IC malfunctional after D3.
