Philip, Jeff,
Please open up a bugzilla.kernel.org report and attach the output from 
acpidump from your machines.

I am hopeful that the "right thin to do" is to not look at bm-status
and that perhaps there is a bug where we are looking at it
"by mistake".

However, it is important that the system be operating properly
when it indeed using c6 as it does with that 1 line patch
earlier in this thread.  So if that patch causes abnormal
operation, please let me know.

thanks,
Len Brown, Intel Open Source Technology Center
