--- Comment #60 from Andriy Gapon <a...@freebsd.org> --- (In reply to Wojciech Giel from comment #59) Thank you! TLDR version of the screenshot for anyone else interested in the problem: one thread panics because it waits "too long" to acquire the ipi spin lock, the lock is held by a thread waiting for the targeted tlb shootdown to be executed by other cpus, the rest of the cpus are idle, acpi_cpu_idle_mwait is used for that.
