Package: src:linux
Version: 6.12.88-1
Followup-For: Bug #1136790
X-Debbugs-Cc: sb@dod.no

Dear Maintainer,

   * What led up to the situation?
Using "apt update" followed by "apt full-upgrade" which upgraded kernel
6.12.86-1 from stable-security with 6.12.88-1 from stable-security
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
After reboot and after logging into the MATE desktop the MX Master mouse failed
to reconnect.

Ineffective first:
Checked the demesg messages about bluetooth and saw that there were fewer
messages than when things were working.

Tried rfkill to unblock bluetooth, but unblocking softblocked bluetooth failed
to make bluetooth working.

Did a full shutdown instead of a reboot, left it down for a while and then
booted. Bluetooth was still not working.

Effective:
Rebooted into the previous stable-security kernel version 6.12.86-1
   * What was the outcome of this action?

Rebooting into kernel 6.12.86-1 made bluetooth working again
   * What outcome did you expect instead?

I expected bluetooth to work in kernel 6.12.88-1
