Package: src:linux
Version: 6.12.6-1
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
I decided to give Trixie a try, to see how well it worked on my computer at 
this stage. After installing Trixie as a secondary OS, I installed my most used 
packaged and made some tests,
then decided to reboot to get back to my every day OS (Bookworm). The reboot 
failed.


   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I tried to reboot from trixie (kernel 6.12.6) using XFCE's reboot option.


   * What was the outcome of this action?
Grub failed. I discovered that my SSD was not seen by the UEFI, which had tried 
to fallback on my (secondary) HDD's bootsector. This disk still
had an old grub bootsector but no usable configuration anymore. The SSD only 
became usable again after I shutdown the computer then cold started it.


   * What outcome did you expect instead?
I expect rebooting to work properly, as it does with bookworm.

I have tried a few things to point to the culprit :

1 - I have looked for telltale errors in journals, with no luck.
2 - I have installed bookworm's 6.1.119-1 kernel : rebooting works.
3 - No that I was reasonnably sure the kernel was the culprit, I tried various 
versions using the snapshots repository :
  _ the last kernel to reboot sucessfully was 6.8.12+1
  _ the first kernel to misbehave was 6.9.7+1

As a result, I think that a regression between 6.8.12 and 6.9.7 causes the SSD 
or its controller to hang during the shutdown for reboot process,
so that at warm restart the UEFI firmware cannot detect it. It seems however 
purely volatile state, since complete shutdown then restart works.
