i'm stumped by this problem.
hardware is SC450NX with 4 CPUs and 2 PCI buses, many SCSI disks, 512M.
kernel is anything from 2.2.late through 2.3.
distribution is RedHat 6.0.
lilo version is 21.
i can't boot the machine without specifying "root=/dev/sda1" on the kernel
cmdline (at LILO: prompt). the last few lines of "make bzImage" look like
this:
make[2]: Leaving directory `/usr/src/linux/arch/i386/boot/compressed'
objcopy -O binary -R .note -R .comment -S compressed/bvmlinux
compressed/bvmlinux.out
tools/build -b bbootsect bsetup compressed/bvmlinux.out CURRENT > bzImage
Root device is (8, 1)
Boot sector 512 bytes.
Setup is 4475 bytes.
System is 710 kB
make[1]: Leaving directory `/usr/src/linux/arch/i386/boot'
bash$
/etc/lilo.conf has this:
boot=/dev/sda
map=/boot/map
install=/boot/boot.b
prompt
compact
timeout=50
read-only
image=/boot/vmlinuz-2.3.39
label=test39
root=/dev/sda1
image=/boot/vmlinuz-2.3.17
label=dev17
root=/dev/sda1
image=/boot/vmlinuz-2.2.13
label=stable13
root=/dev/sda1
without specifying "root=...", the kernel panics on boot with the message
"VFS: Cannot open root device 00:80". i have no idea where it's getting
major=0, minor=128. specifying "root=/dev/sda1" on the LILO: cmdline
allows linux to boot correctly. also the distributed RedHat kernels boot
correctly without "root=..."
any advice or pointers greatly appreciated.
