>Description:
The kernel will not boot if you use a splash screen with, say, 1024x768 resolution and a hint for syscons to start as soon as possible to a higher size. For me I set the syscons hint to 0x1f0 (1366x768)

If /boot/device.hints syscons flags are kept to default, kernel will boot, perhaps screen resolution conflict?
>How-To-Repeat:
Use a BMP splash to 1024*768 256 colors.

# /boot/loader.conf :
splash_bmp_load="YES"
bitmap_load="YES"
bitmap_name="/boot/splash.bmp"

# /boot/device.hints
hint.sc.0.flags="0x180"
hint.sc.0.vesa_mode="0x1f0"

=> Won't boot

>Fix:
Don't know, this is a very complicated issue to fix I guess and user should probably use allscreen_flags in rc.conf instead.
