Missing the 'Call Trace' with the cases of 'KernelOops'

[Cristian Aravena Romero]

Hello,

I am working with these two reports:

* watchdog: BUG: soft lockup - CPU#10 stuck for 22s! [gnome-shell:1112]
https://bugs.launchpad.net/bugs/1796385

* watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [kworker/0:1:85]
https://bugs.launchpad.net/bugs/1797538

And the file: 'OopsText.txt' does not appear in the 'Call Trace'.

Others:
https://bugzilla.kernel.org/show_bug.cgi?id=201379#c3
"The bug in lauchpad, unless I am missing something, provides not a single actionable traceback. I don't think it is even possible to identify where exactly the CPU hangs unless additional information is provided. There is no traceback in dmesg, and OopsText doesn't include it either.

Given that, it is not possible to identify the responsible subsystem, much less to fix the underlying problem. The only thing we can say for sure is that it is _not_ a watchdog driver problem."

Best regards,

Hi, regarding this problem, I started to have the same after upgrading to Ubuntu Cosmic, and it happens each time I wake up the notebook after suspend. So, I close it, I open it and then hard drive hangs. That makes the touchpad not working, so the only thing I can do is to reach the switch off button with the keyboard and restart the system. I hope you can help me, and if you need more information I can give it.

My version is:

This actually looks like an issue with kerneloops which parses dmesg for Call Trace.

[Brian Murray (brian-murray)]

Could you provide the full kern.log file with an OOPS in it? Thanks in advance.
