| |
hi, https://lkml.org/lkml/2011/11/17/54 is the first time I post the question I meet.At that time, I haven't idea to catch it bug! My computer hang too early, and even seral console doesn't help. Recent days I try to compile uvesafb as a module, and insert it when I have a full work kernel, X11, and sshd. Good dog, the bug occurs again, and I catch it! Here are the two patches that I try to fix it, I will appreciate for any comments.Thanks
attached patches: 1/2 x86:add function to check BIOS whether NX 2/2 video:uvesafb: check whether BIOS is NX before try to use PMI
