Sharing my experience in case it helps others or the team working on hardware compatibility.
Hardware
- Framework Laptop 13 (AMD Ryzen AI 300 Series), Version A9
- CPU: AMD Ryzen AI 9 HX 370 w/ Radeon 890M
- BIOS: 03.05 (2025-10-30)
- OS: Ubuntu 24.04.3 LTS (Noble Numbat)
Problem
On kernel 6.14.0-37-generic, my laptop experienced spontaneous hard reboots — no freeze, no warning, just an instant power-off and reboot. The journal cuts off mid-operation
with no panic, thermal event, OOM, or MCE errors logged. No pstore crash dumps were captured either.
These happened during light/normal workloads. Temperatures at the time of the last logged entries were normal (~53C CPU, ~49C GPU).
What I ruled out
- Thermal shutdown — temps well within limits, no thermal warnings in logs
- OOM killer — no OOM events before crash
- MCE / hardware errors — none logged
- Power supply — using a Framework 180W power supply
- Suspend/resume — works correctly, not related
Resolution
I rolled back to kernel 6.14.0-36-generic via GRUB. The system has been stable since Feb 12 with no spontaneous reboots (3+ days uptime as of this post).
I have not yet tested 6.17.0-14-generic (the current HWE kernel available), so I can’t say whether the issue is also present there or was specific to -37.
Possibly related
A ucsi_acpi USBC000:00: unknown error 256 message appears on boot, though this is likely unrelated.
Hope this helps anyone seeing similar behavior. Happy to provide journal excerpts or other details if useful.
