Symptoms

In rare cases, if a 12Gbps SAS PCIe Card, that uses the lsc driver, experiences an abnormal firmware operation (IOC_STATE_FAULT response or no response to the lsc driver) unexpectedly, a SAS Chip Reset will be executed by the lsc driver, causing the disk(s) connected to the 12Gbps SAS PCIe Card to no longer be recognized correctly. This may result in access errors to the disk(s) or data corruption on the disk(s).


This problem does not occur with the 6Gbps SAS driver (mpt_sas).
