I have continued to to look into this and found something. the vchiq driver seems to behave differently under kernel 5.0.3 than it did under 4.20.16. Under both kernels, running the ps command shows the 4 vchiq processes. They are: vchiq-slot/0 vchiq-recy/0 vchiq-sync/0 vchiq-keep/0 For 4.20.16 the processes state code is S (interruptible sleep). On 5.0.3 they are all D (uninterruptible sleep). Any thoughst on if these processes are what are causing the load on my Raspberry PIs to be 4.0 all the time or what to do about it would be greatly appreciated.
