--- Comment #5 from Sergey orbitgray@ukr.net --- Tried to play with rv6xx_dpm_init(), but no luck at all. Toggling init conditions leads to same system stuck.
Though if I put 'return -1' system seems to boot (screen is still off). And I can connect via ssh, but dmesg shows NULL pointer dereference in rv6xx_dpm_ebable(). Probably it is expected if init fails.
