#17 crashinfo --devmapper broken in 5.14+ kernels

[Martin Moore]

crashinfo --devmapper gets the following abort since at least 5.14 (it works in 5.3):

Traceback (most recent call last):
File "/home/martin/pykdump-code/pykdump/highlevel.py", line 730, in whatis
e = crash.gdb_whatis(symbol)
crash.error: PyKdump/GDB error

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
