Hans Hellén, if Hardy's kernel works, but the mainline kernel closest in version number to it doesn't (not the same but similar), it would seem that the sound drivers, and other hardware enablement patches for your hardware were backported to the Hardy kernel, allowing it to work, but mainline wouldn't naturally. Hence, let us put a hold on bisecting the Ubuntu (not mainline) kernel, as that tends to end up in non-linear tag purgatory as per https://wiki.ubuntu.com/Kernel/KernelBisection #Commit_bisecting_Ubuntu_kernel_versions_across_non-linear_tags .
Hence, the issue you are reporting is an upstream one. Could you please report this problem through the appropriate channel by following the instructions _verbatim_ at https://wiki.ubuntu.com/Bugs/Upstream/kernel ? Please provide a direct URL to your e-mail to the mailing list once you have made it so that it may be tracked. Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Confirmed => Triaged -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/882566 Title: [Compal jfl92] CPU stalls in almost every minute: all processing stops, display jams, sound is breaking up. Status in The Linux Kernel: New Status in System76: New Status in “linux” package in Ubuntu: Triaged Bug description: In syslog I was instructed to announce ALSA-developers: snd_pcm_delay returned exceptionally high value. In the same time my VLC player ate all of the available ram and had to be killed. A bug has come back to my Compal JFL92 in 10.04 (I cannot say, was it in the time of release already) and occurs also in live-CD sessions of 11.04 and 11.10. If there is not a continuous input (moving mouse/touchpad or pressing keys), the system kind of jams (in 11.10 my screen jams like a freeze-frame: eg. seconds/minutes in the clock and gnome-system-monitor are not moving) and the music I am listening sounds like coming from a broken CD (skipping/jumping a bit back in 10.04) or like a jammed phonograph/vinyl record (in 11.10). Quite amazing, isn't it? It might have something to do with kernel and chipset/motherboard. I remember, that In 9.04 the OS did not even continue loading if I was not ready to start moving my finger in the touchpad during splash to release the jam.
