https://bugzilla.kernel.org/show_bug.cgi?id=71231 --- Comment #3 from Alex <alexandernaumann@xxxxxx> --- Kernel 3.8.13 is working fine Kernel 3.9.11 is working fine Kernel 3.12.13 has the bug too Kernel 3.13.5 is working fine again. So what has changed in 3.13? It would be nice to have it fixed for the longterm kernel versions 3.10 and/or 3.12. With kernel 3.13 is just get these error messages but the system is not crashing: [ 457.702295] INFO: rcu_sched detected stalls on CPUs/tasks: { 0} (detected by 1, t=2102 jiffies, g=5964, c=5963, q=317961) [ 457.702296] sending NMI to all CPUs: [ 457.702299] NMI backtrace for cpu 3 [ 457.702302] CPU: 3 PID: 1363 Comm: kworker/3:2 Not tainted 3.13.5-64bit #2 [ 457.702303] Hardware name: Dell Inc.
