The kworker has occupied 100% of the CPU for several days:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
68086 root 20 0 00 0 R 100.0 0.0 9718:18 kworker/u64:11
And the stack obtained through sysrq is as follows:
[20613144.850426] task: 8800b5e08000
IO
has not returned here is that the process handling IO in the BM hypervisor
has failed.
The cpu resources of the cloud server are precious, and the server
cannot be restarted after running for a long time. So it's slightly
optimized here to prevent the CPU from being 100% occupied.
