      I guess I've just bad luck, but today I got the following.

        @timschneider Do you have any more details about this bug, i.e. what G-code triggered it? Can you easily reproduce it?

            Ok - so it happend while I was using the filament-error to calibrate the E-Steps and non-linear extrusion. I set the error margin almost to zero +-0.5% and so there are a lot of events generated.

            The following macro can trigger the bug
            Content of 0:/macros/test-event-system.g

            if !exists(global.ignoreMFMevents)
  global ignoreMFMevents = true
else
  set global.ignoreMFMevents = true
  
while iterations < 1000
  M957 E"filament-error" D0 P4 S"tooLittleMovement - The movement is below the minimum set in the R value of M591"

            Contnet of 0:/sys/filament-error.g

            if exists(global.ignoreMFMevents) && global.ignoreMFMevents == true
  M99

            Have at least one DWC session open.
            Call the macro 0:/macros/test-event-system.g

            Result in journalctl

            EDIT: at the second attempt I was not able to reproduce it! Maybe it is related to [warn] Resending packet #1 (request GetObjectModel) as in the first try I saw many of these warnings and after a reboot, these warmings are gone and I can't reproduce the update thread bug.
