The patch attempts to address stability issues by reducing maximum clock frequencies. **Series-level concerns:** 1. **Missing justification**: The commit message lacks critical information about why these specific frequencies were chosen and how stability issues were diagnosed 2. **Lack of testing details**: No information about testing methodology, duration, or workloads used to validate the fix 3. **Potential hardware variation**: No consideration of whether all R5 M420 GPUs need this limitation or if this is specific to certain board designs 4. **Missing documentation**: No explanation of the stability symptoms that motivated this change **Architecture concerns:** - The patch uses PCI device ID and revision matching, which is appropriate for hardware-specific workarounds - The placement in `si_apply_state_adjust_rules()` is correct for the radeon driver architecture - However, this approach may be too broad if only specific board implementations require the limitation --- Generated by Claude Code Patch Reviewer
