I found this in a via forum discussing lockups. "I have kernel 2.6.9-rc1-mm2 running now for more than 2 weeks with enabled longhaul module and frequent cpu-frequency changes (through powersaved). Very important seem to be some patches that are only part of the mm kernel patches. I have tried 2.6.9-rc1 , 2.6.9-rc2 and 2.6.8.1 (with longhaul.c from 2.6.9-rc1-mm2) and all locked the machine up. Some patches inside the mm package seem to be necessary for cpufreq scaling to work without lockups (except for the longhaul.c patch). I guess later mm patches will also work (2.6.9-rc1-mm6, 2.6.9-rc2-mm1)" This is a show stopper for FC3 for anyone using a Via C3 (at least an Ezra-T). Today playing around booting that system I noticed that if I keeped the mouse moving it changed a lockup to a very slow system. Interrupts? Editorial: The Via stuff is becoming a large consumer of my time in testing and installing systems. I see no one from Via actively involved in the community. Sigh! I tried to change the priority of thr bug but it wouldn't let me. I also had installation problems with FC2 on a VIA Eden VE5000 mobo, with a C3 CPU. Installation kernel wouldn't even boot. From the explanation given here: http://www.livejournal.com/users/notbrainsurgery/2429.html it looks like the kernel identifies the C3 CPU as i686 class (which seems correct) but there's an optional characteristic for the i686 arch (conditional movs), which Intel implements and C3 does not, but which gcc assumes to be available for all i686. So RPMs created for the i686 potentially can hangup or reboot the machine, and only i586 RPMs should be used. More info in the link given. BTW, I confirmed the problem by installing FC1 (goes well), installing apt, apt-get dist-upgrading to FC2 and then without rebooting deleting the i686 kernel RPMs and installing the i586 ones. Now it's working ok. It's taken me months to realize this. the installer/up2date shouldn't have installed a 686 kernel on the earlier C3s. There's logic in both to explicitly handle this case. Sounds like apt-get misses the same logic. The original poster. assuming they are using a 586 kernel, might be getting bitten by the longhaul driver, which does seem to have some issues still. Sounds like a dupe of 125419. *** This bug has been marked as a duplicate of 125419 *** |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041016 Firefox/0.10.1 Description of problem: System locks up randomly between 1 and 10 minutes. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Boot system 2. 3. Actual Results: System lockup in 1 to 10 minutes Expected Results: No lockup Additional info: System was stable under FC2. Memtest ran for hours, no errors. Logfile files seem OK except for one kernel warning I caught once that referenced CPUfreq mismatch between actual and expected. Bug 125419 on FC2 seems to be similar on a VIA C3 Samual 2. Its an older bug and still open. I did not have that problem back then.
