Hi does the attach patch fix it? Dave. Same problem. Didn't you reverse the logic on ininterrupt, compared to the old "if (!ininterrupt())" ? It looks like drmcansleep() is false when ininterrupt() is true. I modified your patch as below. Display doesn't freeze, but I still get the warning.

Oh wow I totally screwed up there, you are right, logic inversion.

Can you try the attached?

without the in_interrupt addition.
