Bug Description
The default # of characters allowed in the omap4 kernel is set at 512 according to /usr/src/
Working length:
append vram=32M mem=456M@0x80000000 mem=512M@0xA0000000 fixrtc debian-
Failing length:
append vram=32M mem=456M@0x80000000 mem=512M@0xA0000000 fixrtc quiet debian-
Difference is the addition of "quiet" to reduce the noise level of kernel boot messages.

I believe that this bug was actually caused by CONFIG_SYS_MAXARGS being set too low. It was once 16 but is now 32. This has fixed several other related bugs.
