    1. Cannot boot from /dev/sda2 and /dev/sda3 with 3w-9xxx driver from 2.6
    kernel series. Booting from /dev/sda1 looks to work.

    2. I have a 3w-9000 and the following partitions:

    /dev/sda1 on /boot type ext3 (rw)
    /dev/sda2 on / type ext3 (rw)
    /dev/sda3 on /mnt/debian type ext3 (rw)
    /dev/sda4 on /homes/hirst/dsk1 type ext3 (rw,noatime,data=writeback)
    /dev/sdb1 on /homes/hirst/dsk2 type ext3 (rw,noatime,data=writeback)

    On WhiteBox Linux 3.0. Bootloader is grub (GNU GRUB 0.93) installed in
    /dev/sda.
    The 2.4 drivers that 3ware provides work fine (both with custom and pre
    compiled redhat kernels).
    But if i use a 2.6 kernel with a builtin driver i get a:

    Please append a correct "root=" boot option
    Kernel panic: VFS: Unable to mount root fs on unknown-block(8,2)

    The strange thing is that if i use sda1 as root (801) it's able to mount
    root fs (but obviously fails,
    because it doesn't find init). If i try the same using the driver as
    module and initrd the error is in:
    pivot_root: no such file or directory.

    I tried both stock kernel from kernel.org (2.6.9) and debian
    2.6.8-1smp(precompiled with module driver).

    It looks like the driver recognizes the disks during boot (i get some
    output about 3w-9xxx founding sda and sdb),
    but not the partitions inside the drives (i don't get any output about the
    sda1, sda2, etc...).

    3. Keywords - 2.6, boot, 3w-9xxx
    4. Kernel version - 2.6.9 and 2.6.8-1smp from debian
