Bug Description

This issue was found by the regression test suite.
This test will hang and get killed with our timeout setting.

It's not a regression as I can see that it will time out on older kernels as well. And it can be seen on different releases (although I haven't check if they all have the same dmesg output)

The stalled process will hinder the test for xfs filesystem. As the partition was occupied and cannot be destroyed.

There is a similar bug 1717443
