>Description:
My custom kernel can't get SMBIOS information and can't initialize vga screen.

Even in this state, X will start up on VMware, but on real hardware, a hard reset occurs when X starts.

Curiously, GENERIC or INSTALL kernels work well.

>How-To-Repeat:
Compile the kernel with config like below, and boot the kernel in VMware.
