ry-install — self-contained CachyOS installer + diagnostics for the GTR9 Pro

Sharing a tool I’ve been maintaining since I got my GTR9 Pro running CachyOS. Most of the Linux pain points that come up in this forum (MES firmware crashes, MT7925 WiFi 7 stalls, GPU not staying at high perf, ntsync missing for Proton, etc.) are baked into the fixes here. Posting in case it saves anyone else the rabbit hole.

Repo: https://github.com/ryanmusante/ry-install · Version: v3.3 · License: MIT

It’s a single self-contained Fish script with all 16 config files embedded — no submodules, no external configs to clone alongside it. The script is also a system management tool with status, monitoring, diagnostic, and cleanup utilities tailored for Strix Halo.

Targeted hardware

Component	Spec
CPU	Ryzen AI Max+ 395 (Zen 5, 16C/32T)
GPU	Radeon 8060S (RDNA 3.5, gfx1151, 40 CUs)
Memory	128GB LPDDR5x-8000 (unified)
WiFi	MediaTek MT7925 (WiFi 7)
Ethernet	Dual Intel E610 10GbE

What it fixes

GTR9 Pro symptom on Linux	Fix applied
GPU hangs / MES errors under compute or game load	`amdgpu.cwsr_enable=0`, `gpu_recovery=1`, `runpm=0` (cmdline + modprobe)
MT7925 WiFi 7 stalls and dropouts	`mt7925e.disable_aspm=1`
GPU clocks stuck at `auto` after boot	`amdgpu-performance.service` (Arch #72655 — udev timing unreliable)
CPU stuck at low EPP	`cpupower-epp.service` sets governor + EPP to performance
Wine/Proton fast NT sync missing	ntsync autoload + udev perms (kernel 6.14+)
`sp5100_tco`, `snd_acp_pci`, eSCO dmesg noise	Module blacklist + `bluetooth disable_esco=1`
Slow boot waiting for network	`NetworkManager-wait-online` masked
Sleep/suspend wake issues on new platform	All sleep targets masked (S0ix unreliable)
Random NVMe stalls	`nvme_core.default_ps_max_latency_us=0`

Plus 20 total kernel params, 5 environment vars (RADV/SAM, shader cache, NTSYNC), 13 added packages, 7 removed (incl. power-profiles-daemon, plymouth, ufw).

What’s installed (16 embedded files)

Path	Purpose
`/etc/sdboot-manage.conf`	Kernel cmdline (20 params)
`/boot/loader/loader.conf`	systemd-boot tuning
`/etc/mkinitcpio.conf`	Initramfs (zstd, amdgpu+nvme early KMS)
`/etc/modprobe.d/99-cachyos-modprobe.conf`	Module options + blacklist
`/etc/modules-load.d/99-cachyos-modules.conf`	ntsync autoload
`/etc/udev/rules.d/99-cachyos-udev.rules`	ntsync perms, USB autosuspend off
`/etc/NetworkManager/conf.d/99-cachyos-nm.conf`	iwd backend, powersave off
`/etc/iwd/main.conf`	iwd as NM backend
`/etc/systemd/resolved.conf.d/99-cachyos-resolved.conf`	mDNS off
`/etc/systemd/logind.conf.d/99-cachyos-logind.conf`	Ignore power/lid
`/etc/environment`	Global env vars
`/etc/conf.d/wireless-regdom`	Regulatory domain
`cpupower-epp.service`	Perf state services
`~/.config/fish/conf.d/10-ssh-auth-sock.fish`	SSH agent socket
`~/.config/environment.d/50-gaming.conf`	User-service gaming vars

Quick start

git clone https://github.com/ryanmusante/ry-install.git
cd ry-install
./ry-install.fish     # unattended (progress bar)

Safety

Concern	Handling
Atomic writes	Temp file + `mv` for every install
Validation	All configs syntax-checked before install (mkinitcpio hooks, units, fish, modprobe)
WiFi creds	Never logged, connection file `0600`

Requirements & limits

CachyOS or Arch • systemd-boot • fish 3.4+ • 2GB free on root • AMDGPU only (no Intel/NVIDIA) • ntsync features need kernel 6.14+ • Secure Boot untested.

Tested only on my GTR9 Pro 395 / 128GB. Other Strix Halo SKUs should work but may want threshold tuning. Issues / PRs welcome — particularly from non‑Pro GTR9 owners since I can’t test those.
