The new visibility of RCU processing
Given that the bug seems to have happened on a 3.2 kernel, I suspect that the kthreading is not responsible. ;-)
But here are some commits that have fixed RCU-related CPU stall warning issues in reverse chronological order:
c96ea7cf: rcu: Avoid spurious RCU CPU stall warnings *
c8020a67: rcu: Protect rcu_node accesses during CPU stall warnings
5fd4dc06: rcu: Avoid rcu_print_detail_task_stall_rnp() segfault
a10d206e: rcu: Fix day-one dyntick-idle stall-warning bug *
1c17e4d4: rcu: Prevent uninitialized string in RCU CPU stall info
13cfcca0: rcu: Set RCU CPU stall times via sysfs
2d1dc9a6: rcu: Remove redundant rcu_cpu_stall_suppress declaration
The two commits marked with “*” are the most likely to address this bug.
