Bug ID: 220640
Summary: Hardware: - GPU: AMD Radeon RX 6600 / 6600 XT / 6600M
(Navi 23) - Subsystem: XFX Limited [1eae:6505] -

kernel logs showing context lost events, GPU resets, and SMU/PSP messages.
Hardware:
- GPU: AMD Radeon RX 6600 / 6600 XT / 6600M (Navi 23)
- Subsystem: XFX Limited [1eae:6505]
- Kernel driver: amdgpu
- Kernel: 6.14.0-33-generic
- OS: Ubuntu 24.04 (upstream testing)
Issue:
During normal usage in GNOME, the GPU occasionally loses context, resulting in
visible system issues:
- White, sometimes noisy, screen (GPU output frozen)
- System freeze / unresponsive graphical session
- GPU reset occurs automatically
- Kernel log shows:
amdgpu: The CS has cancelled because the context is lost. This context is
innocent.
amdgpu 0000:09:00.0: GPU reset(2) succeeded!
BACO (Bus Active/Chip Off) for runtime power management is enabled.
Logs indicate repeated SMU / PSP resume sequences and GPU mode resets:
amdgpu 0000:09:00.0: Using BACO for runtime pm
amdgpu 0000:09:00.0: SMU is resumed successfully!
Steps to reproduce:
1. Boot Ubuntu 24.04 with kernel 6.14.0-33-generic.
2. Use system normally (GNOME shell active).
3. Intermittently, observe:
- White / noisy screen
- GPU reset in kernel logs
- Temporary freeze of graphical session
Additional info:
- SMU driver interface version does not match firmware (driver 0x0f, fw 0x13),
but GPU resumes.
- GPU operates normally after reset.
- BACO active for runtime PM.
Impact:
- System instability: freezes, temporary loss of graphical output.
- Potential interference with GPU workloads.
- Annoying / disruptive for desktop usage.
Request:
- Investigate root cause of context loss leading to visible screen corruption.
- Verify interaction with BACO power management.
- Advise on firmware/driver fixes or workarounds.
