Public bug reported:
Hello,
I am experiencing a 100% reproducible kernel regression (on my machine)
that causes an instant system reboot when launching a specific Flatpak
application. The system was previously experiencing random kernel
panics, which were thought to have been resolved by purging a
conflicting system-wide ROCm installation.
What I expected to happen:
The Flatpak application 'Supercell WX' should launch normally.
What happened instead:
The moment the application is launched, the system instantly reboots
without displaying a visual kernel panic message on screen. No "Kernel
Panic" or "BUG" messages are written to the journalctl logs from the
crashed boot; the log simply cuts off.
---
CRITICAL EVIDENCE OF REGRESSION:
---
This crash ONLY occurs on the newer kernel. The application runs
perfectly on the older kernel.
* BAD KERNEL (crashes): 6.14.0-24-generic
* GOOD KERNEL (works mostly perfectly): 6.11.0-29-generic

LOGS:
---
I have attached the required logs version.log and lspci-vnvn.log
(generated while booted into the problematic kernel 6.14.0-24-generic).
version.log file content: Ubuntu 6.14.0-24.24~24.04.3-generic 6.14.6
Due to the nature of the instant reboot, a full crash log is not
available in journalctl. The log from the previous boot journalctl -b
-1) simply ends without any specific error messages related to the crash
itself, showing only normal system activity up to the point of the
reboot.
Thank you for your time.
