Hi,

Are these lock order reversals reported any reason for preoccupation and/or 
should I report elsewhere?

The kernel I just built does not boot at all, so I don´t know whether these are 
a closed issue already. I´m off for a couple of days and will retry then. 

Thanks & regards,

Peter.

      Plus from no 4 onwards with VIMAGE and w/o SCTP option,
      All fs encrypted with geli except /.
