From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3 Description of problem: I have not been able to boot FC3 x86_64 SMP kernels (none of the available, 2.6.9-1.667 and all updates) until I disabled 'cpuspeed' services. Contrary to the somewhat similar problem reported for RHEL4-beta2 (bug #146251), there is no problem to boot the system into uP kernel. That is how I was able to disable cpuspeed. The hangs were at random places after 'cpuspeed' but I have never got to the end of the boot process. After upgrading kernel-utils to 2.4-13.1.49_FC3, apparently the kernel panics immediately after starting 'cpuspeed'. Also, the machine was resetting right after GRUB initial screen when trying to boot SMP kernel after a reboot from uP session (w/o hard reset or power off/on). The reason seems to be that the machine's CPU(s) were left in low-frequency (1GHz instead of nominal 2.4GHz). The BIOS screen shows 1.0GHz until a hard reset. I would suggest adding killproc cpuspeed -USR1 sleep 1 to /etc/init.d/cpuspeed stop() function, just before "killproc cpuspeed -INT" regards, Michal. My machine is dual-Opteron 250, Tyan K8W S2875 MoBo. Fedora Core 3 x86_64. Version-Release number of selected component (if applicable): kernel-utils-2.4-13.1.39, kernel-utils-2.4-13.1.49_FC3 How reproducible: Always Steps to Reproduce: 1. make sure 'cpuspeed' service is "on" 2. boot a SMP kernel Actual Results: system hangs after 'cpuspeed' service is started Expected Results: normal boot Additional info: My machine is dual-Opteron 250, Tyan K8W S2875 MoBo, two 200GB SATA disks, 2GB RAM
Theres a powernow-k8 update pending for upstream cpufreq. I'll pull it in before FC4 final, and if that works out, I'll backport it to the next FC3 update.
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
Finally I was able to test the new kernel (still in FC3). It does not work. Still the machine hangs right after starting 'cpuspeed' during the bootup procedure. I also tried to disable 'cpuspeed' at boot time and to start it manually from the already booted system - I got an immediate kernel panic hang. regards, Michal.
can you capture the panic message ? There's a fix pending that will go in the next FC3 update (I just finished the FC4 test update yesterday, I'll do the FC3 variant next). It'd be good to know if its the same bug.
I have essentially the same problem with fc4 on a similarly configured system. I filed it as bu #166741.
There's at least one panic fix in the latest test kernel in the updates-testing repository. If you could try that out, it may fix your problem.
I am not sure what does "CLOSED ERRATA" status mean, so I am not changing it, but even the lates 1378 kernel does not fix this bug in my machine (described in the first post here). Under SMP kernel, the machine panics immediately after starting 'cpuspeed'.
Are you running the latest BIOS for that board ? There have been a number of issues with Tyan boards that have been unearthed lately. Does it pass an overnight run of memtest86 ?
Dave, we have exchanged a few email on the subject in August. Yes, it has the newest BIOS ver 3.02, and it has passed 40+ hours of memtest (extended tests). Either this type of MoBo/BIOS does not properly support cpuspeed or the particular MoBo is somehow broken (but it otherwise works just fine).
I get a lot of mail :) [which is why keeping stuff in bugzilla is essential, my memory is lossy]. I've no other ideas at the moment.
This is a mass-update to all currently open Fedora Core 3 kernel bugs. Fedora Core 3 support has transitioned to the Fedora Legacy project. Due to the limited resources of this project, typically only updates for new security issues are released. As this bug isn't security related, it has been migrated to a Fedora Core 4 bug. Please upgrade to this newer release, and test if this bug is still present there. This bug has been placed in NEEDINFO_REPORTER state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time.
