Weird issue on #openbsd :
When i change display brightness in xorg, the system hangs for a few seconds.
When i run vmstat during that i get a jump in the run queue:
0 501 2457M 2265M 6 0 0 0 0 0 0 0 30 459 197 0 0 100
7 496 2457M 2265M 9 0 0 0 0 0 0 0 24 318 124 0 42 58
10 492 2457M 2265M 26 0 0 0 0 0 0 0 10 160 38 0 71 29
Everything gets back to normal after that.
edit: this is on a x280
