System hanging when trying to spin-up from HD idle

I've searched an found that sometimes LSI's SAS controllers will hang up when HDs are woken up from an idle state (idled using hd-idle). I'm experiencing this with my pve system. I've even swapped out controller cards using a different LSI controller and the problem persists.

At this point, I believe it might be an issue with pve. Has anyone else experienced this and found a resolution? TIA!
