Fixed In Version: kernel-2.6.32-71.33.1.el6
Doc Type: Bug Fix
Doc Text:
A kernel panic in the mpt2sas driver could occur on an IBM system using a drive with SMART (Self-Monitoring, Analysis and Reporting Technology) issues. This was because the driver was sending an SEP request while the kernel was in the interrupt context, causing the driver to enter the sleep state. With this update, a fake event is now executed from the interrupt context, assuring the SEP request is properly issued.
