Fixed In Version: kernel-2.6.32-71.3.1.el6
Doc Type: Bug Fix
Doc Text:
Previously, the s390 tape block driver crashed whenever it tried to switch the I/O scheduler. With this update, an official in-kernel API (elevator_change()) is used to switch the I/O scheduler safely, thus, the crashes no longer occurs.
