[Bug 138423] Re: [gutsy] Gutsy performance lags dramatically with ACPI enabled
After compiling and installing 'vanilla' kernel 2.6.23.1, my machine runs at full speed again and also suspend to disk RAM both work. I will just hope that the Ubuntu kernel devs are able to ix this sometime in the Gutsy lifecycle. -- [gutsy] Gutsy performance lags dramatically with ACPI enabled https://bugs.launchpad.net/bugs/138423 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 138423] Re: [gutsy] Gutsy performance lags dramatically with ACPI enabled
My laptop has a Pentium III 600 (Coppermine) CPU, and none of the various CPU frequency/scaling kernel modules are loadable. This means that the subdirectories under /sys for controlling throttling etc are non-existent. With ACPI enabled, the kernel seems to run slowly right from the start. When I use 'acpi=off' the system boots at normal speed. -- [gutsy] Gutsy performance lags dramatically with ACPI enabled https://bugs.launchpad.net/bugs/138423 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

http://forums.xandros.com/viewtopic.php?t=30223 See the above thread for details on a bad acpid-CPU throttling problem found in Knoppix and Xandros. With acpi left on, check the scaling_governor mode and also the threshold, and see if the tips at the above link help you any (and of course, report back here). In particular, instead of using the 'performance' setting, you may want to set the threshold to a low value like '20' (worked well for me); A high threshold will kill system responsiveness when the CPU is doing light duty. -- [gutsy] Gutsy performance lags dramatically with ACPI enabled https://bugs.launchpad.net/bugs/138423 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
