 Dear Maintainer, 
  
 with Linux 6.16.3, my system (MSI Bravo Laptop, Ryzen 4800H, Radeon RX 
 5500M) 
 fails to suspend. Suspend works with Linux 6.12.38. 
  
 I'm reporting this on the system while running 6.12.38-1. Below You will 
 find 
 the relevant dmesg output from attemping to suspend using "systemctl 
 suspend" 
 on 6.16.3 and, for comparison, the dmesg output from suspending on 6.12.38.
