[DragonFlyBSD - Bug #2531] camcontrol fails to disable APM
Issue #2531 has been updated by swildner.
OK, I've pushed (and MFC'd) a fix that allows turning off APM for disks at least with nata(4).
I think in order to have have this for AHCI attached disks too (via camcontrol(8)), we'd have to integrate ATA into CAM like FreeBSD did. But I'm not 100% sure about this.
Bug #2531: camcontrol fails to disable APM
I installed dragonfly BSD on an AMD64 laptop but I have a problem.
The hard disk is continuously spinning up and down every few seconds;
on FreeBSD I normally execute the following command to disable APM
#camcontrol cmd ad0 -c "EF 85 00 00 00 00 00 00 00 00 00 00"
but unfortunately it fails on dragonfly with the following error message:
camcontrol: error sending command
