After I rebuilt the system the day before and installed lttng-modules-dkms from Ubuntu officially, the building of kernel modules failed (I can send you the crash and make.log for you to look at). I then added Ubuntu: LTTng Stable 2.13 PPA, and installation passed. With that, what installed are mix/mismatch of kms and binary of the partially installed kms from Ubuntu official and from stable 2.13 ppa. That caused the problem. I now removed everything and reinstalled everything from stable 2.13 ppa, everything works. Thank you for helping me through this.

Hi Kienan,=C2=A0

I just figured o= ut what I did wrong. After I rebuilt the system the day before and installe= d lttng-modules-dkms from Ubuntu officially, the building of kernel modules= failed (I can send you the crash and make.log for you to look at). I then = added=C2=A0Ubuntu: LTTng Stable 2.13 PPA, and installation passed. With tha= t, what installed are mix/mismatch of kms and binary of the partially insta= lled kms from Ubuntu official and from stable 2.13 ppa. That caused the pro= blem. I now removed everything and reinstalled everything from stable 2.13 = ppa, everything works.

Thank you for helping me thro= ugh this.=C2=A0

Best,
Yonghong

Hi Yonghong,

thanks for the extra info. As you say without the symbol resolution the backtrace isn't super useful.

Based on the build-id in the file info for lttng-sessiond, it looks like you might be using the lttng/stable-2.13 ppa.

In that case, you could try using debuginfod with gdb to automatically
download the symbols. See
https://ubuntu.com/server/docs/service-debuginfod for the instructions
enabling the symbol download from Ubuntu's debuginfod server.

thanks,
kienan
