Spontaneous reboots on Framework 13 (AMD Ryzen AI 9 HX 370) with kernel 6.14.0-37-generic — stable on 6.14.0-36

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.

I’ve since updated to 6.17.0-14-generic and haven’t had any reboots. :crossed_fingers:

Yep, you really want up-to-date kernel with modern hardware. Could you update to 6.19.x?
