Ever since 5.x reached stable (haven't tested rc's and such), I get a blank screen every time my laptop returns from suspension. From what I've seen in the logs, it seems the GPU can't get back up.

The full log is attached.

Here is a short info about my system: System: Host: sagan Kernel: 5.0.10-lqx1-1-lqx x86_64 bits: 64 Desktop: KDE Plasma 5.15.4 Distro: Manjaro Linux Machine: Type: Laptop System: LENOVO product: 80XV v: Lenovo ideapad 320-15AST serial: <root required> Mobo: LENOVO model: LNVNB161216 v: SDK0J40700WIN serial: <root required> UEFI: LENOVO v: 5PCN19WW date: 11/29/2017 Battery: ID-1: BAT0 charge: 28.4 Wh condition: 29.9/30.0 Wh (100%) CPU: Dual Core: AMD A9-9420 RADEON R5 5 COMPUTE CORES 2C+3G type: MCP speed: 1397 MHz min/max: 1400/3000 MHz Graphics: Device-1: Advanced Micro Devices [AMD/ATI] Stoney [Radeon R2/R3/R4/R5 Graphics] driver: amdgpu v: kernel Device-2: AMD Topaz XT [Radeon R7 M260/M265 / M340/M360 / M440/M445] driver: amdgpu v: kernel Display: x11 server: X.Org 1.20.4 driver: amdgpu FAILED: ati unloaded: modesetting resolution: 1366x768~60Hz OpenGL: renderer: AMD ICELAND (DRM 3.27.0 5.0.10-lqx1-1-lqx LLVM 8.0.0) v: 4.5 Mesa 19.0.3 Network: Device-1: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter driver: ath10k_pci Device-2: Realtek RTL810xE PCI Express Fast Ethernet driver: r8169 Device-3: Qualcomm Atheros type: USB driver: btusb Drives: Local Storage: total: 111.79 GiB used: 70.03 GiB (62.6%) Info: Processes: 228 Uptime: 5h 19m Memory: 7.18 GiB used: 2.19 GiB (30.5%) Shell: bash inxi: 3.0.33
