An error by SurfaceFlinger going to sleep.

[Masaki Muranaka]

Hello,

I checked android-x86-4.3-20130725.iso and got log like follows.
Is it acceptable this ioctl error? (Or some relation to the sleep/resume issue?)
Thanks.

I/PowerManagerService( 4723): Going to sleep due to screen timeout...
I/WindowManager( 4723): No lock screen!
D/SurfaceFlinger( 4723): Screen released, type=0 flinger=0xb96fdf60
E/SurfaceFlinger( 4723): ioctl(41, VT_RELDISP, 1) failed 22 (Invalid argument)
