Is there an equivalent run-time/boot-time method to set this, like via loader.conf? As far as I can tell this is a compile-time option only but I would like to avoid re-compiling the kernel. I plan to set this to 1 or 2 in conjunction with PUIS to reduce peak boot power for a multi disk system. -- View this message in context: http://freebsd.1045724.n5.nabble.com/CAM-MAX-HIGHPOWER-tp5983034.html Sent from the freebsd-scsi mailing list archive at Nabble.com.
