Hi Christian, Thank you for your guidance and patience throughout this discussion.
After further investigation, I realize that identifying the precise root cause requires a deeper understanding of the DRM subsystem and access to the specific syzkaller reproducer, which I currently lack. To avoid wasting your time with incomplete patches, I'll step back from this issue for now and continue learning the codebase. If I manage to reproduce the problem locally or find more concrete evidence, I'll follow up with a proper analysis. Thank you again for the review and the valuable lessons. Regards, Mingyu
