http://bugzilla.kernel.org/show_bug.cgi?id=11742 Summary: Device buffer on a DVD multi standard writer runs out burning a CD Product: IO/Storage Version: 2.5 KernelVersion: 2.6.27 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: IDE AssignedTo: io_ide@xxxxxxxxxxxxxxxxxxxx ReportedBy: valerio.p@xxxxxxxxx Latest working kernel version: 2.6.26 Earliest failing kernel version:2.6.27 Distribution: Debian Unstable Hardware Environment: Laptop Acer 5920G with a Samsung CDDVDW TS-L632H connected through IDE Software Environment: KDE 3.5.9; k3b 1.0.5; Brasero Problem Description: I have compiled the 2.6.27 kernel using make oldconf, thus almost copying the passed 2.6.26.5 configuration. Since then, when I burn a CD the internal buffer in my DVD burner reaches 0% obliging k3b and brasero to slow down the writing speed. It happens even if I don't run any other application. I have noticed that the device buffer runs out even if the software buffer is full, like there was not a fast transfer from the software buffer to the device buffer. In the end, k3b reports a big amount of buffer under-runs (> 100).Everything works as expected with an older 2.6.26.5 kernel. What I need to do to help solving this bug? See you Valerio Steps to reproduce: Using 2.6.27 kernel and k3b or brasero to burn a CD. It works in simulation mode too (so you don't waste too much CD's ;)) -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
