Turn on CONFIG_DEBUG_INFO to include those debug symbols.

I've not noticed any issues empirically, but I didn't try to measure it. - This config is already succesfully turned on in Hirsute/kvm. + This config is already successfully turned on in Hirsute/kvm. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1935855 Title: dbgsym contains no debug symbols To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-kvm/+bug/1935855/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
