This bug is awaiting verification that the linux-kvm/4.15.0-1100.102 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Turn on CONFIG_DEBUG_INFO to include those debug symbols. [Test Case] Compare: $ file /usr/lib/debug/boot/vmlinux-* /usr/lib/debug/boot/vmlinux-5.4.0-1040-kvm: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, BuildID[sha1]=514891d64a7d18db4fa58aa5cfea213e0951ca9d, not stripped /usr/lib/debug/boot/vmlinux-5.4.0-77-generic: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, BuildID[sha1]=773d8ee85333fe092635f65d2b6850909085c11d, with debug_info, not stripped [What Could Go Wrong] Since linux-kvm is tuned for performance, it's possible there's some side-effect of producing debug symbols that negatively impacts this. 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.
