 Package: src:linux

 Severity: grave 
 Tags: upstream 
 Justification: renders package unusable

 Posting from testing branch: 
  
 Can anyone check to see if this is an issue with how the kernel is being 
 built? 
 With 6.1.0-30-amd64 I don't have these problems. This is being tested on the 
 latest Plasma package. 
  
 I have not yet cherrypicked to see if these problems still occur in unstable 
 and experimental. 
 So far, the situation affects both X11 and Wayland, and can be noticed doing 
 certain actions. 
  
 * Many animations in Plasma appear to lock up for a few seconds and are 
 jerky 
 * Mouse cursor is also jittery and hard to use 
 * Applications fail to completely refresh the screen on time 
 * Logging out back to SDDM casues a kernel panic 
  
 I will obtain crashdump logs as necessary, but for now I am busy. 
 This problem might as well be reported for other Arrandale machines in the 
 meantime...
