Hi all, just to direct your attention to the discussions here: https://bugs.launchpad.net/ubuntu/+source/linux-rt/+bug/290498;
Realtime Ducthman has compiled and made available a build of the rt kernel which seems to work very well (see copy of my latest post below), resolving the iowait issues and such; it's worth a look. ------------------------------------------------------------------------------------------------------------------------------------------------------- Hi, Here are my experiences of using Realtime Dutchman's 25th May build for about 36 hours: Firstly, I am running with a different installation order from RTD: 1. Install 9.04 studio (all multimedia options) - reboot 2. Install all updates - reboot 3. Add workaround for clash involving snd-hda-intel driver and my system (see below) - reboot 4. Install headers 5. Install image - reboot. 6. Enable memlock 50% nice -99 via @ -> System -> Administration -> Ubuntu Studio Controls - Reboot My acpi works infinitely better with kernel than it did without! I have not dared enable wireless yet in any shape or form because the iwl3945 driver seems yet again to be very broken. I will try this later. So far, my system: - Boots - Reboots - Shuts down - ~0% idle CPU - realtime Jack - captures and plays back audio (jack, audacious, audacity, ZynAddSubFx) - suspends, resumes and hibernates (caveat - some processes exit) * IT DOES THESE RELIABLY * This is 100% improvement on the stock studio realtime kernel. My snd-hda-intel needs a tweak to alsa-base.conf and the volume controls, but this is nothing to do with this realtime kernel; it's been a problem with my system at least as far back as hardy: options snd-hda-intel model=dell-m27 enable_msi=0 probe_mask=1 Unmute the capture channel in the standard volume control / alsa mixer. For those interested, without this JACKD watchdog timeouts trying to open the capture channel. My system is as follows: Dell Inspiron 9400 / E1705, 1GB memory, Core Duo 1.8GHz, Intel 945GM graphics, SigmaTel HDA, Intel 3945ABG wireless. ** Attachment added: "lspci -vv output" http://launchpadlibrarian.net/27297847/lspci-vv.txt -- kernel-rt freeze after new install jaunty studio https://bugs.launchpad.net/bugs/366352 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
