Symptoms sound a bit like Bug 513151, but the log output is different. Thanks Nate, I think it must be the same problem since my symptoms are exactly the same. I already replied to the other thread, so I'm marking this one as a duplicate since I think it all ultimately refers to the same issue, even though some log messages might be different. *** This bug has been marked as a duplicate of bug 513151 *** |
Created attachment 187529 [details] CachyOS log of 2025-12-11. When the computer is about to enter scheduled sleep mode, PowerDevil displays an error message in the log and the system freezes, with the only option being to restart the computer: 11/12/25 17:58 org_kde_powerdevil Error detecting VCP version using VCP feature xDF: Error_Info[EIO in ddc_write_read_with_retry, causes: DDCRC_READ_ALL_ZERO, DDCRC_DDC_DATA(2), EIO] 11/12/25 17:58 org_kde_powerdevil [ 1535] Error detecting VCP version using VCP feature xDF: Error_Info[EIO in ddc_write_read_with_retry, causes: DDCRC_READ_ALL_ZERO, DDCRC_DDC_DATA(2), EIO] I've attached the log to this post. It appears to be a regression error; my system was working perfectly until I installed KDE 6.5.4. Here are my system details: Operating System: CachyOS Linux KDE Plasma Version: 6.5.4 KDE Frameworks Version: 6.20.0 Qt Version: 6.10.1 Kernel Version: 6.18.0-5-cachyos (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 8845HS w/ Radeon 780M Graphics Memory: 64 GiB of RAM (59,7 GiB usable) Graphics Processor: AMD Radeon 780M Graphics Manufacturer: GMKtec Product Name: NucBox K8 Plus
