Description James Morris 2007-02-14 10:55:58 EST
Description of problem:

The 2.6.20-1.2925.fc7 kernel does not find my SCSI disks or CD drive, while the
2.6.18-1.2798.fc6 kernel does.

Version-Release number of selected component (if applicable):
2.6.20-1.2925.fc7

How reproducible:

Always

I've attached good & bad boot logs, for the earlier & later kernels respectively.

Here's how the IDE init looks on the good kernel:

ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
SvrWks CSB5: IDE controller at PCI slot 0000:00:0f.1
SvrWks CSB5: chipset revision 147
SvrWks CSB5: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0x08b0-0x08b7, BIOS settings: hda:pio, hdb:pio
    ide1: BM-DMA at 0x08b8-0x08bf, BIOS settings: hdc:DMA, hdd:pio
hdc: SONY CD-RW CRX216E, ATAPI CD/DVD-ROM drive
ide1 at 0x170-0x177,0x376 on irq 15
ide-floppy driver 0.99.newide

Then, the SCSI hardware is not detected either (good version as follows):
mptbase: Initiating ioc0 bringup
input: ImPS/2 Generic Wheel Mouse as /class/input/input1
ioc0: 53C1030: Capabilities={Initiator}
