I have installed FC13 on Sun Fire x4100 platform. I built and installed vanilla 2.6.35.4 SMP kernel and it booted up fine. Then I patched it with patch-2.6.35.4-lttng-0.230 and built and installed the kernel. But it soft locks up while booting. I am attaching the complete console output. Am I missing anything here?

I have installed FC13 on Sun Fire x4100 platform. I built and installed vanilla 2.6.35.4 SMP kernel and it booted up fine. Then I patched it with patch-2.6.35.4-lttng-0.230 and built and installed the kernel. But it soft locks up while booting. I am attaching the complete console output. Am I missing anything here?

I have installed FC13 on Sun Fire x4100 platform. I built and installed vanilla 2.6.35.4 SMP kernel and it booted up fine. Then I patched it with patch-2.6.35.4-lttng-0.230 and built and installed the kernel. But it soft locks up while booting. I am attaching the complete console output. Am I missing anything here?

The soft lockup below looks like it's coming from lvm, not lttng. So I'm
a bit surprised that it works without the patchset and doesn't with the
patchset.
Can you provide your .config for both the kernel that works and the
kernel that doesn't ? Maybe some other kernel option got selected. Also,
please try to disable the added LTTng options (diffing between the two
config files will help you there) to see if it helps.
Another point is to make sure you reinstall your modules too (make
modules_install) when you deploy the lttng-patched kernel, and make sure
you re-create your initrd if you have one.
Thanks,
Mathieu

The difference between the working config (.config.2.6.35.4) and non-working config (.config.2.6.35.4.lttng) is shown below:

So I disabled all LTTNG config variables as follows and rebuilt the kernel. But even this one is having the same soft lockup problem.

I did reinstall the modules and also re-created the initrd. Still the same problem.
The only way I was able to get LTTng patched kernel booted up without soft lockup is with UP kernel (I disabled the SMP in config menu).
