https://bugzilla.kernel.org/show_bug.cgi?id=15623 --- Comment #4 from Anonymous Emailer <anonymous@xxxxxxxxxxxxxxxxxxxx> 2010-03-30 06:24:01 --- Reply-To: Mahesh_Rajashekhara@xxxxxxxxxxx Hi All, We've identified the root cause for this problem. Root cause: This issue is specific to ATA pass-through "CC" bit handling in driver. The in kernel tree driver(build: 24702), the below mentioned conditions were not handled. 1. When the CC bit is SET by the host in ATA pass thru CDB, driver is supposed to return DID_OK. 2. When the CC bit is RESET by the host, driver should return DID_ERROR. We're working on this issue high priority and in the process of preparing the driver patch to address this problem.

Use option -s with argument 'on' to enable it.
