Hell all,
I have a booting problem because the drm driver register a new
framebuffer device after created it. Im not sure if the system blocked
or crashed, because there were no message output after its internal call
to console_lock. I tried marked the booting sequence, and found the
problem at: down(&console_sem);
and in its internal line is: sem->count--; Im not sure why? The fb
device is a dpi device, if I register another device, such as hdmi, it
would be OK.
