Another update: Still experiencing the "freeze" problem. Steps taken since last time I posted an update:
1. Applied fix for slow Wi-Fi problem (Bug #190515). At least this makes machine usable with Wi-Fi connections. Did not fix the freeze problem, though. 2. Installed powertop (which worked even though I have an AMD CPU), and applied all suggestions: Suggestion: increase the VM dirty writeback time from 5.00 to 15 seconds with: echo 1500 > /proc/sys/vm/dirty_writeback_centisecs This wakes the disk up less frequenty for background VM activity Suggestion: enable AC97 powersave mode by executing the following command: echo 1 > /sys/module/snd_ac97_codec/parameters/power_save or by passing power_save=1 as module parameter. Suggestion: Disable 'hal' from polling your cdrom with: hal-disable-polling --device /dev/cdrom 'hal' is the component that auto-opens a window if you plug in a CD but disables SATA power saving from kicking in. However, no luck - machine still freezes up after an hour or so of usage. In fact, occasionally, the freezes are so bad that holding down the "power off" button to switch off the machine doesn't work. I have to disconnect mains power, and remove the laptop battery to get it to power down! Note that the machine did not experience these issues under Gutsy Gibbon and does not experience them under Windows, so am pretty sure that they are Hardy Heron related. My final attempt to fix this will be to move away from proprietary ATI drivers and compiz. If this doesn't work, no choice but to re-install Gutsy. With regard to fixes from the Ubuntu team, suspect that only a few unlucky people have hardware configurations that trigger this problem, so, unfortunately for us, it's not a priority to fix. -- Ubuntu 8.04 Freezes https://bugs.launchpad.net/bugs/228633 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
