System reboot after hung, the soft lockup message keeps come out. since the vmcore not enable before reboot, no vmcore. kernel: 3.10.0-327.el7.x86_64.

If someone has the similar problems before, do you know what the problem was? thanks.

The soft lockup seems to be related to disk I/O request processing. On hardware systems, I would check the SMART data and any other available disk health information to exclude the possibility of a hardware problem.

However, this seems to be a VMware virtual machine, so the first thing to check would be the statistics of the virtualization host: is the host or its storage getting overloaded by all the VMs on it? That could cause long delays in responses to I/O requests. If such a delay lasts over 30 seconds, you'd start getting these soft lockup notifications, even though the root cause might be that there is not enough CPU capacity or storage I/O bandwidth to satisfy the requirements of all the VMs on the host.

  • This kind of errors dispears after release some disks from other VM which at the same host. thanks telcoM.
