It seems to work, but on every | frequency change, everything stalls for 3-4 seconds, even the X mouse | pointer! Keyboard input seems to be buffered though. Is this normal? I found out that the pauses only occur when the X server is running, not when I work on the console, or remotely. I can easily reproduce the problem by playing an mp3 file in a console with mpg321, and then running burnK7 to force frequency scaling. Without X server running, everything works fine, but when the X server is running, the music skips on frequency changes. However, when I start the X server, but switch back to the console with CTRL-ALT-F1, there are no skips. Apparently, some Ubuntu users experienced the same problem: http://ubuntuforums.org/archive/index.php/t-17816.html https://bugzilla.ubuntu.com/show_bug.cgi?id=7121 I already recompiled the kernel with CONFIG_PREEMPT, but that doesn't help. Is this some timing issue in the X server (X.org 6.8.2)? Is there something else to try? -- Dick Streefland //// Altium BV dick.streefland@altium.nl (@ @) http://www.altium.com --------------------------------oOO--(_)--OOo--------------------------- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
