Short description of the paches:
libata-eh.c.patch
This patch is a workaround for the situation when ESATA disk connection leads to kernel panic. Consider the following execution path in driver: libata-core.c:ata_exec_internal_sg -> error during command execution leading to command timeout -> libata-core.c:ata_qc_complete (or ata_port_freeze and finally to the same function) -> libata-core.c:ata_qc_schedule_eh where qc->scsicmd is a NULL pointer by the moment. This patch may not be needed when all hardware/software issues are rectified.
