Version: K3B 1.0.4 (using KDE 3.5.9) Installed from: Mandriva RPMs OS: Linux K3B cannot burn 16x Philips DVD+R with a new hardwre LG GH20NS10 SATA DVD Writer. Operating System: Mandriva Linux Free 2008 Spring DVD Writer: LG GH20NS10 SATA DVD: DVD+R 16x Philips Motherboard: MSI 6590 KT6 Ultra CPU: Athlon XP 2800+ I have tried several combinations, auto-speed recognition and 12x (manual speed). K3B aborts burning. The place of abort is undeterministic. Sometimes it is 10%, sometimes it is 40%. Problem is 100% reproducible. I have also Windows XP installed and I can burn same DVD+R with same hardware without any problem. Please let me know if you want K3B logs. I have stored 2 different cases for you, with screenshorts.
Created attachment 24731 [details] K3B log for auto-speed recognition mode of K3B If you look at the log file, the speed is increasing towards 11.5 but suddenly K3B lost data communication to the hardware (I think), although DVD+R supports up to 16x burn speed and DVD Writer supports up to 20x burn speed. Please note that I have used the same hardware, the same DVD+R on Windows XP and Nero, which came with the DVD Writer, burned this DVD+R without any problem. The files reside on NTFS filesystem in a separate harddisk (/dev/hda). K3B and Mandrive are on EXT3 filesystem in the same harddisk (/dev/hdd).
Created attachment 24732 [details] GUI of K3B when DVD burning aborted (auto-speed mode)
Created attachment 24733 [details] K3B log for 12x manual-speed mode of K3B The same as previous case, but speed is set to 12x.
Created attachment 24734 [details] GUI of K3B when DVD burning aborted (12x manual-speed mode) Same as 24732, but with 12x speed selection.
I have installed 2.6.25.4-1mdv kernel, as suggested by upstream and Mandriva experts. K3B says now DVD wrote successfully but DVD media is corrupt. It cannot be read. uname returns me: [root@localhost mdutku]# uname -a Linux localhost 2.6.25.4-1mdv #1 Sat May 24 16:29:47 EDT 2008 i686 AMD Athlon(tm) XP 2800+ GNU/Linux [root@localhost mdutku]# As soon as K3B finished burning, I have re-inserted the freshly-burned DVD disc. dmesg says me: cdrom: This disc doesn't have any tracks I recognize!

Kernel: Linux localhost 2.6.25.4-1mdv #1 Sat May 24 16:29:47 EDT 2008 i686 AMD Athlon(tm) XP 2800+ GNU/Linux During burning phase for DVD+R K3B 1.0.4 aborts with file I/O error. Linux kernel upstream development team confirmed this is a kernel bug. More information about the kernel bug: http://bugzilla.kernel.org/show_bug.cgi?id=10743
if this is a kernel bug i think we can close this one, what do you think ?
Sorry for late answer. Since the problem of the said DVD writer stated here is actually a kernel bug, I close the case. For more information, please refer to the bug page stated above.
