Bluetooth disabled on zbook ultra with 6.15 kernels (Mediatek 7925)
In any image based on the bazzite 6.15 kernel bluetooth is no longer detected on the zbook ultra, which has the Mediatek 7925. Wireless is still functional on these kernels. Rolling back to any 6.14 based image restores functionality, however these images have more frequent issues with the pageflip_timeout gpu bug, so it's not an ideal solution.

In case anyone runs across a similar issue, I was able to resolve it by disabling bluetooth in EFI, booting to a 6.15 kernel, doing a shutdown (power off) then re-enabling it in EFI.
I've heard of similar issues for people who dual boot, but this is the first time I've encountered it with a linux only device....
