[amdgpu] kernel fault on monitor wakeup, only reboot recovers.

[Harry Coin]

After a normal day's operations, the monitors switch off after an hour or so. Every morning since Impish, upon waking up and unlocking the system: 2 of the monitors wake, the rest remain in sleep mode. The only recourse is to do a graceful poweroff and cold boot. There is a kernel fault, as follows and in the attached file. It is 100% repeatable.

I've been encountering this problem with an RX 6600 using linux-image-5.15.0-22-lowlatency and linux-image-5.15.0-23-generic on Jammy. This had not been happening with linux-image-5.13.0-37-lowlatency on Impish.
