To add more substance, here is what gets logged when the disk disappears:

GEOM_MIRROR: Request failed (error=6). ada0p2[READ(offset=2517700608, 
length=4096)]
GEOM_MIRROR: Device swap: provider ada0p2 disconnected.

And here's what gets logged when the disk reappears:
GEOM_MIRROR: Component ada0p2 (device swap) broken, skipping.
GEOM_MIRROR: Cannot add disk ada0p2 to swap (error=22).
