	Hi Dave,

sorry, in my previous message I forgot the strace
output, which is an inifinite loop of the following:

--- SIGALRM (Alarm clock) @ 0 (0) ---
sigreturn()                             = ? (mask now [])
ioctl(7, 0xc0286429, 0xffdf9bb8)        = -1 EBUSY (Device or resource busy)
--- SIGALRM (Alarm clock) @ 0 (0) ---
sigreturn()                             = ? (mask now [])
ioctl(7, 0xc0286429, 0xffdf9bb8)        = -1 EBUSY (Device or resource busy)

Note: fd 7 is /dev/dri/card0.

	Regards,
	Gabriel
