Bug#1005228: linux-image-4.19.0-18-amd64: Short freeze on virtual machine with message: "rcu: INFO: rcu_sched self-detected stall on CPU"
Hi,
It seems the issue was linked to the 8139cp NIC driver.
I changed the NIC driver to virtio and the stall did not occure anymore.
Let me know if you need more informations about this or if I should signal the issue somewhere else.
Regards,
