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 not executed from the interrupt context, assuring the SEP request is properly issued.

It's hard for us to find a IBM system with a disk having SMART issues, can kashyap or any partner help?

Adam, Same issue with LSI. We don't have required hw too. I see multiple BZ with same question. Shall we mark this as tested by customer once when it was exactly reproduced. Now difficult to create same setup.
