I'm getting the same error on one of my AM3517 boards.
L3_SI_FLAG_STATUS_0 register has bit 15 set that means Display SS IA burst
timeout according to the RM.
Regards, Ilya.
Do the bootloaders on these boards enable display?
There was a patch which got into the kernel in 3.2-rc4:
b923d40dd4211c4ef7d4efa2bd81b7ca1d8744c1
ARM: OMAP2PLUS: DSS: Ensure DSS works correctly if display is enabled in
bootloader
This tries to disable any display outputs if enabled in bootloader. If
this issue didn't happen before, we might want to look into this code.
Could you share what debug prints you get from the function
omap_dss_reset() (its in arch/arm/mach-omap2/display.c)
Thanks,
Archit
