I’ve had a persisting issue with my RX 9070XT and sleep/boot. I regularly have to force restart or power cycle my machine to boot it. I’d like some pointers if anyone can help?

I know its sacrilege here but here’s what cursor AI says about it:

Primary Boot Issues (Most Critical):

  1. AMD GPU Driver Timeouts (Main Issue)
    
    Oct 18 08:17:25 fedora kernel: amdgpu 0000:2f:00.0: [drm] REG_WAIT timeout 1us * 150000 tries - optc401_disable_crtc line:230Oct 18 08:17:27 fedora kernel: amdgpu 0000:2f:00.0: [drm] REG_WAIT timeout 1us * 150000 tries - optc401_disable_crtc line:230
    Hardware: AMD Radeon RX 9070/9070 XT/9070 GRE (Navi 48)
  2. Boot Performance Issues

    Secondary Issues (Non-Critical but Present):
  3. Font Loading Errors
    
    Oct 18 08:17:22 fedora systemd-vconsole-setup[418]: /usr/bin/setfont failed with a “system error” (EX_OSERR), ignoring.Oct 18 08:17:22 fedora systemd-vconsole-setup[428]: setfont: ERROR kdfontop.c:212 put_font_kdfontop: Unable to load such font with such kernel version
  4. Audio Service Assertion Failures
    
    Oct 18 08:17:35 fedora wireplumber[1583]: wp-event-dispatcher: wp_event_dispatcher_unregister_hook: assertion ‘already_registered_dispatcher == self’ failed
  5. USB Device Detection Issues
    
    Oct 18 08:17:27 fedora kernel: usb 5-1: unit 2 not found!
  6. EFI Boot Service Issues
    
    Oct 18 08:17:27 fedora systemd[1]: systemd-boot-clear-sysfail.service - Clear SysFail Entry If The Boot Is Successful was skipped because of an unmet condition check (ConditionPathExists=/sys/firmware/efi/efivars/LoaderEntrySysFail-4a67b082-0a4c-41cf-b6c7-440b29bb8c4f).
    System Information for Forum Post:

    Boot Time: 31.5 seconds total
    Filesystem: BTRFS (healthy, no errors)

    The AMD GPU REG_WAIT timeout errors are the most significant and likely cause of your boot issues. These are common with newer AMD graphics cards and usually indicate driver/kernel compatibility issues.

The reg_wait error used to only happen when sleeping but now it seems to be on a normal boot after a shutdown - unless I empty the board capacitors.

thanks for reading. I can print what I did to get the conclusions if it helps?
