CONFIGURATION To force legacy interrupts for all isci driver instances, set the follow- ing tunable value in loader.conf(5): hw.isci.force_legacy_interrupts=1 DEBUGGING To enable debugging prints from the isci driver, set the hw.isci.debug_level variable to a value between 1 and 4 in loader.conf(5). The hardware layer in the isci driver has extensive logging capabilities which are disabled by default for performance reasons. These can be en- abled by adding options ISCI_LOGGING to the kernel configuration file.
