Red Hat Bugzilla – Bug 319441
kernel chooses wrong clock source
Last modified: 2008-04-06 14:43:08 EDT
Description of problem:
During boot on my IBM X40 laptop, the installer hangs at "running /sbin/loader",
and goes no further for several minutes. During this time, console 3 lists a
number of modules loaded, and several inserted, ending with /tmp/loop.ko.
Console 4 has normal looking kernel messages ending with:
<4>loader used greatest stack depth: 2296 bytes left
<6>loop: module loaded
After several minutes, the installation process continues.
dmesg reports "Clocksource tsc unstable (delta = -139639622012 ns) " after
"loop: module loaded". If I boot the system with the kernel option
"clocksource=acpi_pm", I don't have this problem.
Version-Release number of selected component (if applicable):

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the Fedora kernel.
I am CC'ing myself to this bug and will try and assist you in resolving it if I can.
There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?
If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.
I *think* this was resolved before the final F8 release. If it comes up when I
test F9, I'll reopen this bug.
Please do Gordon. I'm closing WORKSFORME at the moment - you can also test with
a 2.6.24-based kernel from rawhide if you wish.
Please, don't shoot the messenger, but I was just hit by this when I booted with
Fedora 9 Alpha 1 DVD. Symptoms are exactly the same as in Comment 1 and in my
earlier report in Bug 322411.
Strangely enough, there has been no such problems with any Fedora 8 kernels
after its installation.
Oh, well, I can't reopen this bug. I'll reopen my earlier Bug 322411 instead, then.
Re-opening per comment #8, changing version to rawhide
I'm happy to inform that this bug is not present in Fedora 9 Beta!
Awesome! I'll go ahead and close this bug then.
