Since the kernelci email report went out, another lab reported a PASS for this board on the same defconfig, so this particular FAIL is likely a lab-specific issue, so I wouldn't let this block stable release. FYI... I have a few other boards[1] that are failing in mainline with CONFIG_PROVE_LOCKING=y, and I've yet to get to the root of the problem. My best guess currently is that those seem to be related to the bootloader/boot-firmware not being able to deal with large zImage (CONFIG_PROVE_LOCKING makes a bit bigger image.) I don't know the closed bootloader/boot-firmware on these qualcomm platforms, so I've asked the qcom maintainers for some help.
