Comment 2 Randy MacLeod 2021-06-17 14:55:38 UTC 
If you see this again, get the qemu guest dmesg output and paste it here. We suspect that the guest kernel is crashing.

Sakib, Can we dump the qemu log file if this happens?
Comment 3 Richard Purdie 2021-06-28 10:27:16 UTC 
Closing as likely caused by rcu stall hangs. Without the kernel logs we can't tell. We'll open new bugs if issues recur.
