Anyone success with 440GR Rev.B (1.1)?

[Andriy Korud]

Hi,
I have complete system (U-Boot, Linux, userspace) running on 440GR Rev.A. 
However after mounting newer chip revision (Rev.B, 1.1) U-Boot and Linux boots fine, however when trying to execute first userland application (init), I get:

Freeing unused kernel memory: 112k init
init has generated signal 4 but has no handler for it
Kernel panic - not syncing: Attempted to kill init!

I've tried everything - different compilers (3.x, 4.1.x), deifferent kernels (2.6.18, 19) - problem is 100% reproducible. Even when replaced busybox with printf("hello world") - the same. 
According to AMCC changelog and erratas there are no changes in CPU core between revisions. 

Anybody has an idea what should I check/try?

Thanks in advance,
