kdump on RHEV with HPE servers using hpsa and vdsm enabled may fail with an NMI IOCK and not capture vmcores

Solution Verified - Updated -


There is an interaction with vdsm and the HPSA driver that somehow leads to an NMI IOCHK.
This can hang the vmcore capture process and fail to capture a vmcore.


  • RHV 4.2 Host (both RHEL or RHVH) with vdsmd running
  • HPE servers with hpsa driver
