Not in the three days that I've been running 5.2 kernels with the hack applied
(so that should be about twelve hours of proper uptime).

Sure. On 5.1.17 I get:
Sink support: yes [0x01]
PSR mode: PSR1 enabled
Source PSR ctl: enabled [0x81f00626]
Source PSR status: IDLE [0x040b0001]
Busy frontbuffer bits: 0x00000000

And, in case you need it, on 5.2.1+hack I get:
Sink support: yes [0x01]
PSR mode: PSR1 enabled
Source PSR ctl: enabled [0x81f00626]
Source PSR status: IDLE [0x04030006]
Busy frontbuffer bits: 0x00000000

Hope this helps,


Paul
