I retested total 272 times with CONFIG_FB_EFI=n on the machine that can easily
reproduce this bug, and the 10 times on other two machines, all of them booted
successfully.Excuse me, I think it's a little hard to make sure this config
works on _all_ machine, because this issue can't be reproduced for every
reboot, even on the machine that can easily reproduce this issue. If this is
not enough to prove config works. I need some time to satisfy your requirement.
