Is this a regression? What was the last kernel version that worked? Could you bisect?

It is a new mini pc. I only tested with Arch Linux kernel 6.9.7.arch1-1 but the bluetooth device was not supported. Then I tested 6.10.0-rc5-x86_64 and 6.10.0-rc6-x86_64 kernel. Both have the same hibernate/resume problem.
