Masking Radeon HD 7570 as 6570 just makes the machine stuck at gIOScreenLockState3 with light gray flashing over the verbose seconds before gIOScreenLockState3.

This is on macOS High Sierra and above.

Tried to use it on Monterey with OCLP, same issue.

High sierra vanilla, same issue

Whats the problem? The 6570 is the same as the 7570 with a device ID change.
