Update: from several weeks that I have been trying to find a solution on this.
- New Kernel doesn't work (latest kernel from Ubuntu repository) - I thought the problem came from pulseaudio, so I removed it and used Alsa instead. The bug still occurs. - "CE: hpet increased min_delta_ns" happens most of the time when the system hangs, and I use "dmesg" command. - trying to disable hpet (use hpet=disable in Grub) doesn't work. Also changed laptop's clocksource to acpi_pm doesn't work either. (my machine only have 2 clocksources : hpet, acpi_pm) - VLC actually does not involve in the bug, but Adobe Flash might - restarting the machine quickly after the crashes does not reset the problem. when the system came back, CPU is still slow. I have to wait awhile anyway to get the CPU frequency comes back up. - Re-install with Ubuntu 10.10 32bit version, still happens. - I currently moved to Linux Mint 10, with Kernel 2.6.35-22. The problem still occurs. My way to reproduce the bug is playing several Flash VDO at the same time (like playing different tabs of youtube in Chrome) or One divx vdo on VLC and one youtube vdo. While the CPU load, memory, caches are rising up, the CPU frequency will be going down. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/680418 Title: vlc scaling down CPU speed -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
