+ | * fwupd can be used for firmware upgrades | ||
+ | ===== Issues/ | ||
+ | === issue: high load === | ||
+ | I had issues with the first Thinkpad T590 I received, on Fedora31: | ||
+ | * the rngd daemon did keep one or more cores busy after some system boots | ||
+ | * error messages like the following appearedon my Wayland/ | ||
+ | < | ||
+ | [drm: | ||
+ | [drm: | ||
+ | [drm: | ||

+ | [drm: | ||
+ | </ | ||
+ | * sometimes, after boots, the system was not showing the above errors/no high cpu usage from rngd, and just running fine. | ||
+ | * eventually, after updating firmware with fwupd, the system did not come back into a usable state. Pushing the off-button for many seconds did turn the system off. When then turned on, the screen did not light up. | ||
+ | |||
+ | === solution === | ||
+ | * Lenovo business service dissected the system, assembled it, and it became usable as before. | ||
+ | * At a second visit, the motherboard was exchanged. Since then, the issues and error messages are gone. | ||
+ | |||
+ | === issue: frequent docking station disconnects === | ||
+ | The docking station was connected to the T590 and I got these disconnects in 3sec timeframes: | ||

+ | |||
+ | === solution === | ||
+ | For now, connecting the rj45 network cable directly into the Thinkpad T590, instead of the docking station, seems to fix this. |
