Problem: RAID auto-detect on my promise PC20378 doesn't seem to work - but works with other controllers. First of all - thanks to Mark Hahn for emailing me off list and helping me out a bit. I think it's time to bring this back to the list. It seems that, at least in my configuration, kernel raid auto-detection runs before the kernel has detected partitions on the SATA Promise driver (note: pata chain on the SATA controller). Dmesg showing this below. I have a RAID-1 array between partitions on a disk on a 82801EB/ER (ICH5/ICH5R) IDE Controller and my SATA Promise PDC20378 controller. I have all the required parts BUILT IN to the kernel (kernel config below). My 82801EB/ER (ICH5/ICH5R) IDE Controller seems to be run by the general IDE layer - I have no particular drivers enabled. My Promise PDC20378 is controlled by CONFIG_SCSI_SATA_PROMISE with the libata1.patch from Jeff in order to support the PATA part of the controller. Again, built in, NOT a module. RAID1 support is also built in. What happens is: Recongize ICH5/ICH5R Initialize partitions on ICH5/ICH5R Recognize PDC20378 Raid auto-detect Recognize partitions on PDC20378 Dmesg: http://www.phildev.net/dmesg.txt Kernel Config: http://www.phildev.net/config-2.6.15.6rider-smp lspci: [phil@rider ~]$ lspci 0000:00:00.0 Host bridge: Intel Corporation 82865G/PE/P DRAM Controller/Host-Hub Interface (rev 02) 0000:00:01.0 PCI bridge: Intel Corporation 82865G/PE/P PCI to AGP Controller (rev 02) 0000:00:1d.0 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #1 (rev 02) 0000:00:1d.1 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #2 (rev 02) 0000:00:1d.2 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #3 (rev 02) 0000:00:1d.3 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #4 (rev 02) 0000:00:1d.7 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB2 EHCI Controller (rev 02) 0000:00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev c2) 0000:00:1f.0 ISA bridge: Intel Corporation 82801EB/ER (ICH5/ICH5R) LPC Interface Bridge (rev 02) 0000:00:1f.1 IDE interface: Intel Corporation 82801EB/ER (ICH5/ICH5R) IDE Controller (rev 02) 0000:00:1f.3 SMBus: Intel Corporation 82801EB/ER (ICH5/ICH5R) SMBus Controller (rev 02) 0000:00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02) 0000:01:00.0 VGA compatible controller: nVidia Corporation NV36.2 [GeForce FX 5700] (rev a1) 0000:02:03.0 FireWire (IEEE 1394): VIA Technologies, Inc.
