Subject: scripts/gdb: received an error when invoking lx-symbols

Hi Jan, Kieran,
with the last Linux 5.8-rc6 I have some problems with gdb scripts.
Everything is fine with Linux 5.7.

When I call lx-symbols, I received this error while loading modules
symbols:

    (gdb) set python print-stack full
    (gdb) target remote :1234
    Remote debugging using :1234
    arch_atomic_read (v=<optimized out>) at ../arch/x86/kernel/process.c:687
    687		trace_cpu_idle_rcuidle(PWR_EVENT_EXIT, smp_processor_id());
    (gdb) lx-symbols

    gdb.error: There is no member named name.
    Error occurred in Python: There is no member named name.

I'll try to bisect.

Thanks,
Stefano
