Public bug reported:
After updating to linux HWE 6.14.0-33 (linux-image-6.14.0-33-generic),
iwd crashes when attempting to start and connect to wifi. The kernel
produces the attached crash, which shows it is a result of calling
usercopy_abort. The last working HWE kernel 6.14.0-29 does not exhibit
this problem.
