From babe668c21283a412fc558d40b4f87fd33b69260 Mon Sep 17 00:00:00 2001 From: Wei Hui Date: Fri, 14 Oct 2016 11:24:51 +0800 Subject: [PATCH] Delete kernel debug related parameter for performance Those deleted kernel parameters are extremely heavy debug. The boot process is rather slow on machines which has a complicate motherboard and lots of pci devices(Lenovo RD640). The debug process costs so much resouce, evetually it will impact normal functions, such as cpus are so busy dealing with debug info in kernelspace, they do not have time to reponse udev event in userspace and failed to bring up pci devices.
