Subject: [virtio-net] BUG: sleeping function called from invalid context at
kernel/mutex.c:616
Greetings,
I got the below dmesg and the first bad commit is
commit 3ab098df35f8b98b6553edc2e40234af512ba877
Author: Jason Wang <jasowang@...hat.com>

virtio-net: don't respond to cpu hotplug notifier if we're not ready
We're trying to re-configure the affinity unconditionally in cpu hotplug
callback. This may lead the issue during resuming from s3/s4 since
- virt queues haven't been allocated at that time.
- it's unnecessary since thaw method will re-configure the affinity.
Fix this issue by checking the config_enable and do nothing is we're not ready.
The bug were introduced by commit 8de4b2f3ae90c8fc0f17eeaab87d5a951b66ee17
(virtio-net: reset virtqueue affinity when doing cpu hotplug).
