This could indicate a real problem. It means that the core was 
unexpectedly reset at some point. This is checked in cache_as_ram.inc. 
Look for 	/* check if cpu_init_detected */.

If the reset is intentional, the reset code should set/clear the bit in 
the msr by calling set_bios_reset();

I have seen unintentional resets caused by AP init and/or CAR and memory 
init issues. You can get into some funny race conditions with AP and BSP 
using the same CAR location but that is just a guess.

I hope that gives you some ideas about what might be going wrong and 
where to start looking.
