It is now fixed in Fedora 15 32bits but not in Ubuntu 32 and Ubuntu 64
(2.6.38-10.46). All 3 are running on the same PC.

Also tvtime is not causing the problem. tvtime uses the v4l device
video0. It seems tvtime runs fine as long as no application attempts to
open the CX88 mpeg device /dev/video1. However normally the v4_id
process attempts to open it during the boot sequence. All process trying
to open /dev/video1 hang immediately and after that has happened
processes trying to open /dev/video0 also hang.

If v4_id is not run during the boot sequence (this happens sometimes on
Ubuntu 32 boot, I don't know why), it is possible to run tvtime or touch
/dev/video0 safely. But if one try then to opens /dev/video1 with "touch
/dev/video1", then after that running tvtime or touch /dev/video0, the
process hangs.
