Hi! I've got a "Bull Express5800/Series" (dual P3) with a DAC1164 RAID controller. The mainboard is ServerWorks based and however, 2.4.2-pre3 fails to find the RAID controller. I think there's a problem at scanning PCI busses behind PCI bridges. Here's the PCI bus layout as 2.4.0-test10 recognizes it: -+-[01]-+-04.0 Adaptec 7899P | +-04.1 Adaptec 7899P | \-0a.0-[02]--+-08.0 Digital Equipment Corporation: Unknown device 1065 | \-09.0 Mylex Corporation eXtremeRAID support Device \-[00]-+-00.0 Relience Computer CNB20HE +-00.1 Relience Computer CNB20HE +-02.0 ATI Technologies Inc 3D Rage IIC 215IIC [Mach64 GT IIC] +-03.0 Intel Corporation 82557 [Ethernet Pro 100] +-06.0 Intel Corporation 82557 [Ethernet Pro 100] +-07.0 Intel Corporation 82557 [Ethernet Pro 100] +-0f.0 Relience Computer: Unknown device 0200 \-0f.1 Relience Computer: Unknown device 0211 Here's log output from both 2.4.0-test10 (successfully booting) and 2.4.2-pre3 (no success due to missing root fs): ----------------------- 2.4.0-test10 ----------------------- PCI: PCI BIOS revision 2.10 entry at 0xfdb3c, last bus=2 PCI: Using configuration type 1 PCI: Probing PCI hardware PCI: ServerWorks host bridge: secondary bus 00 PCI: ServerWorks host bridge: secondary bus 01 PCI->APIC IRQ transform: (B1,I4,P0) -> 16 PCI->APIC IRQ transform: (B1,I4,P1) -> 17 PCI->APIC IRQ transform: (B2,I8,P0) -> 20 PCI->APIC IRQ transform: (B0,I2,P0) -> 19 PCI->APIC IRQ transform: (B0,I3,P0) -> 18 PCI->APIC IRQ transform: (B0,I6,P0) -> 26 PCI->APIC IRQ transform: (B0,I7,P0) -> 23 [...] DAC960: ***** DAC960 RAID Driver Version 2.4.8 of 19 August 2000 ***** DAC960: Copyright 1998-2000 by Leonard N.
