Adaptec 7XXX/DPT SmartRAID V

[gnu_is_not_unix <gnu_is_not_unix@wp.pl>]

Hello dear linux-scsi subscribers,

I got machine with squid and apache. It is a normal PC (2x550PIII, 400MB ram, SCSI adaptec 2940,
DPT SmartRAID V Controller, network card ...) - nothing special.

System is rh 7.3 with updates and rh kernel (2.4.18 not compiled by my self i mean).
Partitions with system are on the disk on adaptec, directory for squid cache
on DPT SmartRAID V Controller (raid 0 - 4 x 18 GB)

I got one problem with this configuration. When I try to boot from "my
self" compiled kernel (2.4.18), as first controller, linux recognize DPT,
so my root partitions can not be mounted (can not find root fs etc./etc.).

Booting from rh kernel gives good results:

[root@bishop root]# mount
/dev/sda7 on / type ext2 (rw,nosuid)
none on /proc type proc (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
/dev/sda1 on /boot type ext2 (rw,nosuid,nodev,noexec)
/dev/sdb1 on /cache type reiserfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
none on /dev/shm type tmpfs (rw)
/dev/sda8 on /tmp type ext2 (rw,nosuid,nodev,noexec)
/dev/sda6 on /usr type ext2 (rw,nosuid,nodev)
/dev/sda5 on /var type ext2 (rw,nosuid,nodev,noexec)

BIOS shows good order - adaptec is the first, dpt - second.

I know that i can do some workarounds with lilo but it is not good solution i think.

Am i missing something ?

ps. sorry for my poor english.
