[Bug 374284] Re: Jaunty Upgrade: Really REALLY sucky performance with rt kernel
Hi teledyn, This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/lucid. If it remains an issue, could you run the following command from a Terminal (Applications-Accessories-Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux 374284 Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results. Thanks in advance. [This is an automated message.

[Bug 374284] Re: Jaunty Upgrade: Really REALLY sucky performance with rt kernel
thanks for the rename ;) a possible cause: the Dell Inspiron 1521 uses the Radeon X1200 graphics for which the geniuses at AMD just clipped support in the fglrx driver, so that means the only acceptable performance is with the radeon driver (I haven't yet tried radeonhd with a non-RT kernel) and the radeon is unable to move bits fast enough to play full-screen AVI files and keep the sound synchronized. Perhaps that situation is made worse with a RT kernel? -- Jaunty Upgrade: Really REALLY sucky performance with rt kernel https://bugs.launchpad.net/bugs/374284 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

purged the machine of all RT kernel images and modules, then reinstalled using aptitude install linux-rt and it seemed to work, the machine rebooted and was reasonably speedy until I tried to enter text into this form, then it started to slow down dramatically; I tried to test the playback of a youtube page, but didn't get very far -- on entering text into the firefox location bar, the CPU halted, no ctrl-alt-del, no response from the off switch. so something is desperately wrong with the RT kernel in the Jaunty environment. don't know if drm or the radeon modules were loaded, but I think they must have been to have given the good performance for the first few minutes of us (in the situation that started this ticket, performance was bad right from the login and even in svga mode) -- Jaunty Upgrade: Really REALLY sucky performance https://bugs.launchpad.net/bugs/374284 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

24 hrs later and the machine has been performing perfectly since switching to the generic kernel. perhaps the subject of this bug should be changed to: Where do we get a working RT kernel for Jaunty? and maybe a side bug to report that the upgrade fails to recognize that the RT support will result in an unstable machine. -- Jaunty Upgrade: Really REALLY sucky performance https://bugs.launchpad.net/bugs/374284 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

[Bug 374284] Re: Jaunty Upgrade: Really REALLY sucky performance
one culprit was the RT kernel installed by Ubuntu-Studio Linux uhuru 2.6.24-23-rt #1 SMP PREEMPT RT Wed Apr 1 23:40:34 UTC 2009 I removed this and installed Linux uhuru 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 and performance is immediately much improved, Xorg shows drm now installs and radeon and drm are now both in the lsmod listing. the upgrade apparently misses replacing the RT kernel, which makes sense (in retrospect) since Cannonical does not support the RT kernel images. -- Jaunty Upgrade: Really REALLY sucky performance https://bugs.launchpad.net/bugs/374284 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
