 +===== Generic hints =====
 +  * Fedora31 and later are great on the hardware
 +  * fwupd can be used for firmware upgrades
  
 +===== Issues/solutions =====
 +=== 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/sway setup:
 +<code>
 +[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe B (start=7699 end=7700) time 3583 us, min 1192, max 1199, scanline start 1091, end 118
 +[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe B (start=7953 end=7954) time 3566 us, min 1192, max 1199, scanline start 1103, end 131
 +[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe B (start=7967 end=7968) time 7303 us, min 1192, max 1199, scanline start 959, end 4
 +[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe B (start=7979 end=7980) time 3666 us, min 1192, max 1199, scanline start 943, end 952
 +[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe B (start=8042 end=8043) time 3639 us, min 1192, max 1199, scanline start 1039, end 72
 +[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe B (start=8152 end=8153) time 3599 us, min 1192, max 1199, scanline start 1020, end 51

 +  * 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:
 +<code>
 +[ 2905.676673] usb 1-5.3.3.1: USB disconnect, device number 78
 +[ 2905.850691] usb 1-5.3.3.1: new full-speed USB device number 79 using xhci_hcd
 +[ 2905.928808] usb 1-5.3.3.1: New USB device found, idVendor=17ef, idProduct=a38f, bcdDevice= 0.00
 +[ 2905.928814] usb 1-5.3.3.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
 +[ 2905.928816] usb 1-5.3.3.1: Product: Billboard Device
 +[ 2905.928818] usb 1-5.3.3.1: Manufacturer: Cypress Semiconductor
 +[ 2905.928819] usb 1-5.3.3.1: SerialNumber: 0001
 +[ 2905.933369] hid-generic 0003:17EF:A38F.0048: hiddev97,hidraw4: USB HID v1.11 Device [Cypress Semiconductor Billboard Device] on usb-0000:00:14.0-5.3.3.1/input1
 +</code>
 +
 +=== solution ===
 +For now, connecting the rj45 network cable directly into the Thinkpad T590, instead of the docking station, seems to fix this.
