<div dir="ltr"><div>Hi, I have a suspend issue using mainline kernel 3.12.02 on Ubuntu 13.10. I am using the latest coreboot branch and the latest seabios branch. I have built coreboot using the reference tool set. The issue is that the system suspends but upon resume the kernel oops. The hardware is an Acer C7 Parrot board. I have attached the kernel config, coreboot config and the kernel oops message log. Thanks for your help.<br>
