I am on a core i7 system bl67 intel board and it all keeps oopsing on me. On 3.2.33 I get on 3.6.6 I get rcu errors (though rcu stress test didn't show anything) or traces that include cpuidle / apic. Does anyone have an idea what that could be? The system is just running a plain console and some disk i/o is going on all the time. Thanks, Soeren slab error in verify_redzone_free(): cache `radix_tree_node': memory outsid= e object was overwritten Pid: 0, comm: swapper/3 Not tainted 3.2.33 #1 Call Trace: [] ? __slab_error.isra.53+0x1b/0x30 [] ? cache_free_debugcheck+0x27e/0x280 [] ? __rcu_process_callbacks+0x174/0x390 [] ? kmem_cache_free+0x5b/0x1e0 [] ? __rcu_process_callbacks+0x174/0x390 [] ? __do_softirq+0x95/0x120 [] ? lapic_next_event+0x18/0x20 [] ? clockevents_program_event+0x6f/0x110 [] ? call_softirq+0x1c/0x30 [] ? do_softirq+0x65/0xa0 [] ? irq_exit+0x8e/0xb0 [] ? smp_apic_timer_interrupt+0x68/0xa0 [] ? apic_timer_interrupt+0x6e/0x80 [] ? intel_idle+0xed/0x160 [] ? intel_idle+0xcb/0x160 [] ? cpuidle_idle_call+0x8b/0x100 [] ? cpu_idle+0x6a/0xf0 ffff8801ba9366d8: redzone 1:0xd84156c5635688c0, redzone 2:0xf14156c5635688c= 0. slab error in verify_redzone_free(): cache `radix_tree_node': memory outsid= e object was overwritten Pid: 16, comm: ksoftirqd/3 Not tainted 3.2.33 #1 Call Trace: [] ? __slab_error.isra.53+0x1b/0x30 [] ? cache_free_debugcheck+0x27e/0x280 [] ? __rcu_process_callbacks+0x174/0x390 [] ? kmem_cache_free+0x5b/0x1e0 [] ? __rcu_process_callbacks+0x174/0x390 [] ? __do_softirq+0x95/0x120 [] ? run_ksoftirqd+0x10a/0x230 [] ? __do_softirq+0x120/0x120 [] ? __do_softirq+0x120/0x120 [] ? kthread+0x7e/0x90 [] ? kernel_thread_helper+0x4/0x10 [] ? kthread_worker_fn+0x180/0x180 [] ? gs_change+0x13/0x13 ffff8801ba936248: redzone 1:0xd84156c5635688c0, redzone 2:0x964156c5635688c= 0. slab error in verify_redzone_free(): cache `radix_tree_node': memory outsid= e object was overwritten Pid: 0, comm: swapper/3 Not tainted 3.2.33 #1 Call Trace: [] ? __slab_error.isra.53+0x1b/0x30 [] ? cache_free_debugcheck+0x27e/0x280 [] ? __rcu_process_callbacks+0x174/0x390 [] ? kmem_cache_free+0x5b/0x1e0 [] ? __rcu_process_callbacks+0x174/0x390 [] ? __do_softirq+0x95/0x120 [] ? lapic_next_event+0x18/0x20 [] ? clockevents_program_event+0x6f/0x110 [] ? call_softirq+0x1c/0x30 [] ? do_softirq+0x65/0xa0 [] ? irq_exit+0x8e/0xb0 [] ? smp_apic_timer_interrupt+0x68/0xa0 [] ? apic_timer_interrupt+0x6e/0x80 [] ? intel_idle+0xed/0x160 [] ? intel_idle+0xcb/0x160 [] ? cpuidle_idle_call+0x8b/0x100 [] ? cpu_idle+0x6a/0xf0 ffff8801ba9366d8: redzone 1:0xd84156c5635688c0, redzone 2:0xf04156c5635688c= 0. slab error in verify_redzone_free(): cache `radix_tree_node': memory outsid= e object was overwritten Pid: 0, comm: swapper/3 Not tainted 3.2.33 #1 Call Trace: [] ? __slab_error.isra.53+0x1b/0x30 [] ? cache_free_debugcheck+0x27e/0x280 [] ? __rcu_process_callbacks+0x174/0x390 [] ? kmem_cache_free+0x5b/0x1e0 [] ? __rcu_process_callbacks+0x174/0x390 [] ? __do_softirq+0x95/0x120 [] ? lapic_next_event+0x18/0x20 [] ? clockevents_program_event+0x6f/0x110 [] ? call_softirq+0x1c/0x30 [] ? do_softirq+0x65/0xa0 [] ? irq_exit+0x8e/0xb0 [] ? smp_apic_timer_interrupt+0x68/0xa0 [] ? apic_timer_interrupt+0x6e/0x80 [] ? intel_idle+0xed/0x160 [] ? intel_idle+0xcb/0x160 [] ? cpuidle_idle_call+0x8b/0x100 [] ? cpu_idle+0x6a/0xf0 ffff8801ba936248: redzone 1:0xd84156c5635688c0, redzone 2:0x964156c5635688c= 0.
