Hello,

After upgrading to 6.16.9 this morning, my laptop can't boot. I cannot 
get any logs because the kernel seems to freeze very early, even before 
I'm asked for the full disk encryption passphrase.

This is a regression from 6.16.8 to 6.16.9.

I did a git bisect in the stable/linux and this is the commit causing 
the issue for me:

97207a4fed5348ff5c5e71a7300db9b638640879 is the first bad commit
commit 97207a4fed5348ff5c5e71a7300db9b638640879 (HEAD)

     drm/xe/guc: Enable extended CAT error reporting

     [ Upstream commit a7ffcea8631af91479cab10aa7fbfd0722f01d9a ]

https://lore.kernel.org/all/20250625205405.1653212-3-daniele.ceraolospurio@intel.com/

How to reproduce:

1. Upgrade to 6.16.9
2. Enable the Xe driver by passing i915.force_probe=!7d55 
xe.force_probe=7d55
3. Reboot

Best regards,
Iyán
