On my system growisofs fails to write a pre-mastered ISO image with the following error message: # /usr/bin/growisofs -dvd-compat -overburn -Z /dev/dvd=dvd-1.iso Executing 'builtin_dd if=dvd-1.iso of=/dev/dvd obs=32k seek=0' :-( failed to create thread: Input/output error There's propably a patch (haven't tried it yet, going to bed now): http://www.mail-archive.com/cdwrite%40other.debian.org/msg11671.html Arch: ppc (Power PC 32-bit) If you need emerge --info (though I doubt it) let me know.
*** This bug has been marked as a duplicate of bug 197670 ***
Bug 197670 has different error messages when invoked as normal user vs as root. This bug on the other hand has an I/O error, regardless who's running growisofs. So is it really a dublicate?
Fixed with app-cdr/dvd+rw-tools-7.0-r1 (dvd+rw-tools-7.0-thread-stack-size.patch), which is at this time ~ppc.
