I try to discover why the device name changed and find something.
I run lspci and find 2 ide interface, as show below:
00:05.0 IDE interface: Silicon Image, Inc. PCI0680 Ultra ATA-133 Host
Controller (rev 02)
/sys/block/hda/device/driver->../../../../../bus/ide/drivers/ide-disk
00:0f.1 IDE interface: Broadcom CSB6 RAID/IDE Controller (rev a0)
/sys/block/hda/device/driver->../../../../../bus/ide/drivers/ide-cdrom
So, I disable the cdrom in bois. The hard disk name is /dev/hda now.
Question is: what is the order kernel detect the hardware? when will
it detect cdrom before hard disk and assign name hda to cdrom?
