Comment 11 for bug 989547

Tested the suspend-resume with the same image on 4460, and I wasn't able to reproduce the issues with USB.

However I got the following issues:
1 - With pvr-omap4 (SGX) I had the same issue as described by bug 916135
2 - Without pvr-omap4 (just using fbdev) I got the following messages with my monitor:
...
[ 131.013793] omapdss OVERLAY error: overlay 2 horizontally not inside the display area (1629 + 64 >= 1024)
[ 131.023864] omapdss APPLY error: failed to enable overlay 2: check_settings failed
[ 131.032531] omapdss OVERLAY error: overlay 2 horizontally not inside the display area (1623 + 64 >= 1024)

[ 131.051208] omapdss OVERLAY error: overlay 2 horizontally not inside the display area (1610 + 64 >= 1024)
...
And nothing was happening on the screen. After switching to the console's virtual terminal and X11, it got back to work as expected.

Then on both cases I got the following warnings, which is probably harmless:
