Thanks, this confirms my suspicion:

ioctl(9, 0x40086485, 0x7fffa426f020) = ? ERESTARTSYS (To be restarted)
--- SIGALRM (Alarm clock) @ 0 (0) ---
rt_sigreturn(0xe) = -1 EINTR (Interrupted system call)
ioctl(9, 0x40086485, 0x7fffa426f020) = ? ERESTARTSYS (To be restarted)
--- SIGALRM (Alarm clock) @ 0 (0) ---
rt_sigreturn(0xe) = -1 EINTR (Interrupted system call)

Somebody who understand these ioctls() should try to figure out why it
never succeeds.
