Linux 6.12.1 won't wake up after suspend.

orangecza · 2024-11-24 15:19:23

AMD 7600X with MSI B360 motherboard

sudo journalctl with linux 6.12.1:

systemd[1]: Starting System Suspend...
systemd-sleep[281]: Successfully froze unit 'user.slice'.
systemd-sleep[281]: Performing sleep operation 'suspend'...
kernel: PM: suspend entry (deep)

(No more journal. The whole system goes into sleep, and it never wakes up.)

sudo journalctl with linux-lts 6.6.63:

Does Linux 6.12.1 have bugs on suspend?

Same issue here

Had the issue with Fedora 41 too on the latest kernels, switched to Arch because of that, it stopped working now...

Operating System: Arch Linux
KDE Plasma Version: 6.2.3
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0
Kernel Version: 6.12.1-arch1-1 (64-bit)

Processors: 32 × AMD Ryzen 9 7950X 16-Core Processor
Memory: 62.4 GiB of RAM
Graphics Processor: AMD Radeon RX 7800 XT

```
Nov 24 16:22:08 archbox systemd[1]: Reached target Sleep.

```

For me it rebooted after trying to wake up, the KDE lockscreen also appeared but then everything locked up.

Okay so, I tried something. I disabled the bluetooth service (sudo systemctl disable bluetooth --now), and now sleep works again.

Can you check if you also have Bluetooth enabled?

I have two Lenovo ThinkPad E14 AMD G4 which only differ in their Wifi/Bluetooth-card. One is affected by this, the other isn't. I can confirm that stopping `bluetooth.service` is a work-around for this issue.

This is the *unaffected* card:

```
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8852BE PCIe 802.11ax Wireless Network Controller
Subsystem: Lenovo Device 4853
Physical Slot: 0
Flags: bus master, fast devsel, latency 0, IRQ 72, IOMMU group 11
I/O ports at 2000 [size=256]
Memory at fd400000 (64-bit, non-prefetchable) [size=1M]
Capabilities: [40] Power Management version 3
Capabilities: [50] MSI: Enable+ Count=1/1 Maskable- 64bit+
Capabilities: [70] Express Endpoint, IntMsgNum 0
Capabilities: [100] Advanced Error Reporting
Capabilities: [148] Device Serial Number 00-e0-4c-ff-fe-88-52-01
Capabilities: [158] Latency Tolerance Reporting
Capabilities: [160] L1 PM Substates
Kernel driver in use: rtw89_8852be
Kernel modules: rtw89_8852be
```

This is the *affected* card:

```
03:00.0 Network controller: MEDIATEK Corp. MT7921 802.11ax PCI Express Wireless Network Adapter

Kernel driver in use: mt7921e
Kernel modules: mt7921e
```

After searching the forums, this comes up with a possible fix: https://bbs.archlinux.org/viewtopic.php?id=295916

Edit: The second solution from https://github.com/alimert-t/suspend-fr … or-mt7921e seems like a good automation for the work-around in my case (first solution did not work).

Yep, I have an AMD/Mediatek one

Also having the MT7921e driver loaded

❯ lsmod | grep mt7921e

I edited my post with a possible workaround (not my idea),

gromit · 2024-11-24 21:46:46

So which was the last version that still worked for you? Was it one of the 6.11.9 series or one even before that?

matteodev · 2024-11-25 17:34:07

Before 6.11.9 (On Fedora at least), it might be one of the early 6.11 ones

gromit · 2024-11-25 17:40:24

Could you verify this by installing the latest version out of the 6.10 series?

sudo pacman -U https://archive.archlinux.org/packages/l/linux/linux-6.10.arch1-2-x86_64.pkg.tar.zst
