The patch reduces maximum clock speeds from 850/1000MHz to 800/950MHz (core/memory) to address stability issues. **Overall Assessment: NEEDS WORK** The patch addresses a legitimate stability concern, but has several issues that need to be addressed before it can be merged: 1. **Missing justification**: No explanation of why these specific clock values were chosen or what testing was performed 2. **Incomplete commit message**: Lacks hardware details, symptom description, and testing methodology 3. **Hardcoded values without documentation**: Magic numbers with no explanation 4. **Potential scope concern**: Only targets one specific revision; unclear if other R5 M420 variants exist 5. **Missing references**: No bug reports, user reports, or hardware documentation cited --- Generated by Claude Code Patch Reviewer
