Does anyone have some insight as to why the newer kernels 2.4.19/2.4.20 seem to have issues with the promise raid controllers. Everything works fine with 2.4.18: CONFIG_BLK_DEV_ATARAID=y CONFIG_BLK_DEV_ATARAID_PDC=y # CONFIG_BLK_DEV_ATARAID_HPT is not set CONFIG_BLK_DEV_PDC202XX=y CONFIG_PDC202XX_BURST=y CONFIG_PDC202XX_FORCE=y CONFIG_BLK_DEV_ATARAID_PDC=y Kernel 2.4.18: Promise Fasttrak(tm) Softwareraid driver for linux version 0.03beta PDC20267: IDE controller on PCI bus 00 dev 10 PDC20267: chipset revision 2 PDC20267: not 100% native mode: will probe irqs later PDC20267: ROM enabled at 0xfe8e0000 PDC20267: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER Mode.
