Thanks, solved the issue for me. I further investigated the 
7.0ish-kernel panic:
panic: kernel diagnostic assertion "ram_size <= KERNEL_VM_BASE - 
KERNEL_BASE" failed: file 
"/usr/src/sys/arch/evbarm/gumstix/gumstix_machdep.c", line 487

My first assumtion the ram size calculation was off, isn't correct. The 
values are:
ram_size: 134217728 KERNEL_VM: 0xc1000000 KERNEL_BASE: 0xc0000000

Thus I think the KASSERT seems odd (or I mistaken the values). If the 
RAM size is bigger or equal the estimated kernel space (~16MB) the 
kernel panics. Sadly after changing the line to:
KASSERT(ram_size > KERNEL_VM_BASE - KERNEL_BASE);
the boot hangs later. I currently investigating where in the subsystems. 
Somewhere after "cache(l1pt)" but before "special".

But it would be kind if somebody could have a look at this KASSERT. I'm 
not sure why other GUMSTIX-board can boot with this line in place.

Thanks & Best Regards
