Hi:

I have a dual Xeon with an Adaptec 200S zero-channel raid controller
running the 2.4.21 kernel.  I want to try a patch that requires
2.4.23-rc-1.  However, when I build the kernel, it won't boot.  I simply
took the .config from the 2.4.21 kernel and ran make oldconfig.  I have
tried this with 2.4.22 unpatched and patched to 2.4.23-rc1.  When the
2.4.21 machine boots, I get these messages:

However, when the non-working kernels boot, this happens before the
loading Adaptec I2O Raid message (this message never appears).

kmod: failed to exec /sbin/modprobe -s -k block-major-8 errno=2
VFS: Cannot open root device "sda2" or 08:02
Please append a correct "root=" boot option
kernel panic: VFS: Unable to mount root fs on 08:02

The following options are enabled:

Adaptec AACRAID support
Adaptec AIC79xx support
Adaptec I2O Raid support
I2O support
I2O PCI support
I2O Block support
I2O LAN support
I2O SCSI support
I2O /proc support

I have tried this with the support in the kernel and as modules.  The
same thing happens each time.  Is there something I have done wrong or
is this broken?
