Subject: In slow QEMU: task rb_producer:17 blocked for more than 120 seconds.
Hi Steven,
Two of my test boxes run the slower QEMU VMs and the guest kernels
often trigger warnings like:
[ 511.809001] Testing event mm_vmscan_memcg_reclaim_end: [ 512.852980] INFO: task rb_producer:17 blocked for more than 120 seconds.
[ 513.279212] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
Will it be possible to insert some break into the test thread for
avoiding the warnings?
Thanks,
Fengguang
