[1.] One line summary of the problem:

A page fault occurs when the sound driver is loaded.

[2.] Full description of the problem/report:

A page fault occurs when the sound driver for Intel Commet-Lake platform is loaded. This happens e.g. on Lenovo ThinkPad X13 and T14 at startup and version 1.4.3 of intel-sof-firmware binaries (https://github.com/thesofproject/sof-bin/tree/stable-v1.4.3). Same result with version 1.5.1.
