I have successfully run apport-collect from a working 6.8.0-71-generic kernel
(Ubuntu 24.04.3 live installer).
Please note: The issue described in the bug only occurs when booting kernel
6.14.0-27-generic (Ubuntu 25.04 live/installer and upgraded systems).
The uploaded logs therefore do not show the crash itself, but they contain
complete hardware and configuration information.
The failure with 6.14.0-27-generic still happens exactly as described in the
initial report.

Title:
Ubuntu 24.04 fails to boot with kernel 6.14.0-27-generic on ASRock
GENOAD8X-2T/BCM – reboots after systemd init
Status in linux package in Ubuntu:
Confirmed
Bug description:
Ubuntu 24.04 LTS fails to boot with the kernel linux-
image-6.14.0-27-generic on an ASRock Rack GENOAD8X-2T/BCM motherboard
equipped with an AMD EPYC 9104 CPU. The system enters a reboot loop
shortly after early systemd initialization. Several systemd messages
are briefly shown, followed by an immediate reboot. This behavior
continues indefinitely.
Steps to Reproduce:
1. Update to Ubuntu Server 24.04 LTS or boot the official 24.04
LTS Live/Installer ISO.
2. Use hardware with ASRock Rack GENOAD8X-2T/BCM and AMD EPYC 9104.
3. Boot the system using the default kernel (6.14.0-27-generic).
4. Observe that the system starts systemd, then abruptly resets,
repeating in a loop.
Expected Result:
The system should boot to a login prompt or installation interface.
Actual Result:
After several systemd messages (ending with Reached target Local Encrypted
Volumes.), the system reboots without explanation, and the cycle repeats
indefinitely.
Additional Details:
• Kernel 6.8.0-71-generic works without issue.
• Affected even when booting from Live/Installer ISO — this is
not installation-specific.
• Crash logs are not generated.
• Boot parameters (noapic, nomodeset, etc.) do not mitigate the
issue.
• BIOS configuration has been reviewed and reset to defaults.
• Attached: archive with hardware/grub info + boot failure video
(.mov).
