System hangs with following message:

BUG: unable to handle page fault for address: ffffb6740145f39f

This on a Tuxedo Infinity laptop, kernel 5.9.x are all OK.

I'm experiencing the same issue, as shown on this camera shot of the issue:

Not sure if it's exactly the same, but similar on boot full stop workqueue lockup of the CPU.

Lenovo Yoga C740-14IML

Booting with Kernel 5.9.14 remains fully functional.

I have a strong suspicion that this is related to bluetooth. Once the bluetooth service starts, or btintel modules are loaded, that's when the boot process fails and starts throwing fits.

And I noticed in this posting https://lwn.net/Articles/835774/ there was some significant changes in 5.10 regarding ABI and bluetooth.

Does the workaround mentioned in https://bugzilla.opensuse.org/show_bug.cgi?id=1180344#c16 work for you?
