ioctl(5, 0x806c4120, 0xbffeffd0) = -1 ENODEV (No such device)

about 70 times a second.
Of course, with other software, it may be different.

Yes, this is certainly not the bug then. The bug exists regardless,
but it's not what you're hitting.
(I wonder then if mplayer has the opposite problem caused by erroring
out on EPIPE: randomly terminating in the middle of playback 'every
now and then')
