queued internally. This works around issue in the isci HAL where it cannot accept new I/O to a device after a resetting->ready state transition until the completion context has unwound. This issue was found by submitting non-tagged CCBs through pass(4) interface to a SATA disk with an extremely small timeout value (5ms). This would trigger internal resets with I/O in the isci(4) internal queues. The small timeout value had not been intentional (and original reporter has since changed his test to use 5sec instead), but it did uncover this corner case that would result in a hung disk.

FreeBSD Driver for Intel(R) C600 SAS Controller =============================================== This driver has been developed for use with FreeBSD, version 9.0 and later. This driver uses an OS-agnostic abstraction layer library named SCIL that is published by Intel specifically for the C600 SAS controller. The SAS controller has no firmware, so the driver is extensive and using SCIL minimizes the development and maintenance cost of the driver. The FreeBSD implementation files are in the isci directory, and SCIL files are in the isci/scil subdirectory. As Intel publishes new versions of SCIL (to add features or fix bugs), the isci/scil subdirectory will be updated appropriately.
