Porting both is definitely the right call 009836b4 fixes the stopper thread deadlock when migrate_swap() races with hotplug, while c861cac9 fixes RCU state corruption from calling rcu_momentary_eqs() with interrupts enabled inside multi_cpu_stop().
They fix two different race conditions in the exact same multi_cpu_stop() path, so backporting both together is much safer :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2163642 Title: Kernel panic "Attempted to kill the idle task" on AMD Opteron multi- node NUMA under KVM (6.8.0-137) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2163642/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
