Follow up, I tried to use the growisofs on a dvd+rw disc and this is the only output from dmesg: VMBlock warning: DentryOpRevalidate: invalid args from kernel VMBlock warning: DentryOpRevalidate: invalid args from kernel VMBlock warning: DentryOpRevalidate: invalid args from kernel VMBlock warning: DentryOpRevalidate: invalid args from kernel Growisofs told me it was restarting in dvd-rw mode and then the driver just started clicking, about 6 clicks and a buzz, 6 - buzz and on and on and on. I had to ssh in from another machine then teleinit to 3 then eject cdrom before it would let it go. -- John Registered Linux User 263680, get counted at http://counter.li.org
