RTL8852BE fails to power on: "xtal si not ready" on ASUS TUF GAMING B650-PLUS WIFI

[Jason Kakandris]

System Info

Distro: Linux Mint 22.3 Zena (Ubuntu 24.04 base)
Kernels tested: 6.14.0-37-generic, 6.17.0-14-generic (same failure on both)
Motherboard: ASUS TUF GAMING B650-PLUS WIFI (Rev 1.xx)
BIOS: v3827 (Feb 2026)
CPU: AMD Ryzen 7 7700X
Driver: rtw89 v7.0 (git commit d2f175e
https://github.com/morrownr/rtw89/commit/d2f175eafa0a4ef9cc65e7073a77e60238cae614)
WiFi works in Windows: Yes


Problem
The RTL8852BE WiFi card fails to initialize with xtal si not ready error. No
wireless interface is created.

What I've tried

Kernel parameter pcie_aspm=off

disable_ps_mode=y
Updated BIOS from v3057 to v3827
Updated firmware files via make install_fw
Tested on kernels 6.14 and 6.17 — same failure on both

WiFi works fine in Windows on the same hardware

It looks like you didn't encounter D3Cold problem, but I think you can
give it a try [1].

These messages appear when first booting or after system resume?
Recently we update something related to suspend/resume problem.
Please use the latest driver (kernel 7.0-rc4) with the latest
firmware (v0.29.29.15).

As you try this, please ensure that add a configuration file to /etc/module.d/,
and cold reboot.

Hello!

- The error appears on first boot, not after resume. It has never
worked on Linux.
- I have set up a udev rule to disable D3Cold for the device and will
test with a cold boot. I will also try the latest firmware
(v0.29.29.15) and report back.
Where can I obtain firmware v0.29.29.15? Is it rtw8852b_fw-2.bin from
linux-firmware.git?

Yes. 

I review the "xtal si not ready" messages again. It looks like it fails to
power-on before downloading firmware, so firmware might not the cause
you are encountering. 

Please try to remove module and reinstall module after booting to see how
it will be. Open a terminal, manually do below commands (try more than
one times), and share kernel log to us

  rmmod rtw89_8852be
  modprobe rtw89_8852be
