ProbeLabs65 findings · 95 requirementsA proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.
T2 iMac20,1 stuck at loading bar after linux-t2 7.2.4 (amdgpu SMU regression)

Original report
System details
Apple iMac20,1 (Retina 5K 27" 2020), AMD Navi 14 Pro 5300 1002:7340, Omarchy 4.0.3, linux-t2 from arch-mact2 repo, linux-firmware 20260810-2
What's wrong?
After omarchy-update pulled linux-t2 7.2.3.arch1-2 → 7.2.4.arch1-1, reboot sticks at the Plymouth loading bar. System is up (SSH works, systemctl is-system-running = running), but no graphics:
- amdgpu: SMU: No response / Failed to setup smc hw / Fatal error during GPU init / probe failed -62, no /dev/dri
- SDDM stuck after Logind interface found, never Adding new display
- plymouthd SIGSEGV
Downgrading to 7.2.3.arch1-2 from pacman cache restores the desktop. Only linux-t2 + headers changed, so this is a kernel regression landing via update. Suggest holding linux-t2 at 7.2.3 for T2 Macs until fixed upstream.
BAD (7.2.4):
kernel: amdgpu 0000:03:00.0: SMU: No response msg_reg: 6 resp_reg: 0
kernel: amdgpu 0000:03:00.0: Failed to setup smc hw!
kernel: amdgpu 0000:03:00.0: probe with driver amdgpu failed with error -62

kernel: amdgpu 0000:03:00.0: SMU is initialized successfully!
kernel: amdgpu 0000:03:00.0: [drm] Display Core v3.2.384 initialized on DCN 2.0
