Hi I have the following questions: 1. Is it possible to (temporarily) disable the SATA hardware from generating interrupts (either the controller or the actual HDD)? 2. if so, how? 3. if so, is it safe? My setup is as follows: Modules loaded: ata_piix, libata, scsi_mod, ahci (ahci doesn't seem to be used) SATA controller (from lspci): 00:1f.2 IDE interface: Intel Corporation 82801FBM (ICH6M) SATA Controller (rev 04) HDD: Hitachi Travelstar, model HTS541080G9SA00 Reason: I am building a real-time system using RTAI. I do not need to access the HDD while in real-time mode, but I must access another peripheral which shares the interrupt with libata. I want do disable the libata interrupts while in real-time mode, to improve the timing characteristics of the real-time peripheral.
