Can someone point me to some documentation that explains how the spl interrupts work? For example, in the Scsi code (scsi_scsi_cmd in scsi_base.c) just before a command is sent to the adapter, a call is made to splbio(). Does this mask all I/O interrupts? Network interrupts too? Thanks. Michael Vernick
