February 27Feb 27 After upgrading from Unraid 7.2.3 to 7.2.4 yesterday, the system fails to boot with the error "RCU-preempt detected stalls on CPUs/tasks".I have already tried rewriting the boot USB drive with the 7.2.4 image, but the issue persists.Attached is the full error screenshot. Any suggestions on how to fix this or roll back properly?

February 27Feb 27 Community Expert Can you try to boot unraid on a different computer with that flash drive? That will help decide if the flash drive works .
February 28Feb 28 Author Solution I was able to resolve the issue.The root cause was related to CPU C-states on my AMD platform. After disabling CPU C-states in the BIOS, Unraid boots normally without any failure.Thanks everyone for the help!
