i'm having a strange problem trying to boot a custom built 2.4.19 kernel
on a Psyche system. the Red Hat 2.4.18-17.8.0smp kernel works fine on this
system but a custom built kernel fails to mount root device during boot.
the kernel source tree is unmodified and has been configured to include
DAC960 (Mylex AcceleRAID 160) driver and ext2/ext3 support as static
modules.
the root filesystem is on a ext3 partition and the other filesystems are
on LVM logical volumes (see mount output).
i'm using Grub for booting (relevant parts of grub.conf below).
here're the kernel messages from the failed boot sequence, any ideas on
what's wrong here?
