I drop into DDB and put 'bt' console photo in the very first message of 
this thread - nothing unusual seen in the main stack. Could you please 
specify exact DDB commands you want to be issued by me? No dump can be 
provided since nothing is mounted yet including swap,

BTW, I remember I saw previously unseen warnings with post Jun 14 kernels:
"xpt_action_default: CCB type 0xe not supported"

'ps' inside DDB shows [xpt_thrd] at "ccb_scan" wmesg state and [g_event]
at "caplck" wmesg state, [kernel] at "g_waitid" state.
Even don't know, if it matters.
