To me, that looks like a vmware problem.

When I googled "linux RCU" it says Read-copy update (RCU) is*a scalable high-performance synchronization mechanism implemented in the Linux kernel*. This journal entry also made me think it is a kernel issue RIP: 0010:rcu_sched_clock_irq+0xb2c/0x1120 I was thinking it was the 6.6 kernel because it is supposed to include a new CPU scheduler which promises to improve performance and reduce latency and those messages, especially the RIP message sound like they might be related to that but I don't know if TW has it enabled, still researching that. -- Regards, Joe
