Removing the option to get back to /dev/ad4* doesn't fix the problem. BTW ATA_CAM seems to work fine with generic ATA but not with ataintel. > Possibly this is the source of the problem (specifically, it looks like > FreeBSD doesn't have proper device ID knowledge of what this controller > is. I believe that's because this system is *very* new, a Core i3/i5/i7 > system)? I didn't notice that, you're right! The system is brand new, got it delivered on Tuesday. Another odd thing is that the controllers have differents IDs, 0x3b208086 vs 0x3b268086. I added the IDs to ata-intel.c and it fixes the problem. Preparing a patch.
