Subject: [irqdomain]  08d85f3ea9:
 Kernel_panic-not_syncing:timer_doesn't_work_through_Interrupt-remapped_IO-APIC


FYI, we noticed the following commit:

commit: 08d85f3ea99f1eeafc4e8507936190e86a16ee8c ("irqdomain: Avoid activating interrupts more than once")
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq/urgent

in testcase: hackbench
with following parameters:

	cpuset.mems: 0-$((nr_node-1))
	cpuset.cpus: 0-$((nr_cpu-1))
	nr_threads: 1600%
	mode: threads
	ipc: pipe
	cpufreq_governor: performance

test-description: Hackbench is both a benchmark and a stress test for the Linux kernel scheduler.
test-url: https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/sched/cfs-scheduler/hackbench.c


on test machine: 32 threads Intel(R) Xeon(R) CPU E5-2680 0 @ 2.70GHz with 32G memory
