Hi,
the lx commands(like lx-symbols) were failing in gdb with the following error: loading vmlinux Python Exception <class 'gdb.MemoryError'> Cannot access memory at address 0xffffffff828da7a0: Error occurred in Python: Cannot access memory at address 0xffffffff828da7a0
the python script is loaded in gdb (/home/jo/linux-5.12/vmlinux-gdb.py) the CONFIG_RANDOMIZE_BASE is disabled and CONFIG_FRAME_POINTER is enabled
kernel config: https://gist.githubusercontent.com/1Jo1/0d455013f31bb42ec68715ac7ff10db7/raw/7501b404abdfb6949d13df97216f4cace3192f2e/qemu-kernel-gdb-debugging
I followed these instructions https://www.kernel.org/doc/html/latest/dev-tools/gdb-kernel-debugging.html
I have the same issue with older kernels, probably I missed something?
