I have tested this patch and there is my result:


Linux kernel patch solves the problem of stopping while playing after
2min 40sec.

gnome-media/tcd/linux-cdrom.c with fix http://bugs.gnome.org/db/33/33600.html
solves the problem of fast-fwd. Even on older kernels ffwd works OK.

Both these were two independent bugs, one in kernel, second in tcd.


I have looked into GNOME CVS and nobody have yet comitted this patch
into CVS, so I am doing it.

Can anybody close the bug in GNOME bug tracking system?
