I think the problem is KALSR. You have to disable it
disabling the kernel option "Randomize the address of the kernel image (KASLR)", inside Processor type and features. In this way, gdb can translate all the symbols correctly.
The easiest way to disable KASLR is to start the kernel with the option nokaslr (simply add nokaslr to the kernel command line in grub or any other boot manager).
