Hi,
I'm trying to install Slackware 13.37 on my Laptop (Thinkpad W520). I am installing it on my external hard drive. The problem is after installation, when I try to boot I get an error "Kernel Panic - not syncingL VFS: Unable to mount root fs on unknown-block(*,*)" ((0,0), (8,19), I have seen different codes). The filesystem on all my partitions (/ and /boot) are all ext4. I have Windows-7 and Ubuntu on my primary hard drive. I have tried installing the OS multiple times with different lilo configurations such as No lilo, lilo on MBR, lilo on /, etc. (I prefer grub so 'no lilo' is my preferred choice). Plus I also created a bootable usb for slackware.

When I boot for slack, I have tried 'mount root=/dev/sdb3 ro' where 'sdb3' is my root directory for slackware. Just to leave no chance of the bootable usb taking up 'sdb', Have also tried '/dev/sdc' but no avail. One suggestion that I have read is adding 'rootdelay=10', but I have no clue how to add it. (I tried mount root=/dev/sdb3 rootdelay=5 rw). So can anyone guide me with this. I also did a update-grub, but the same error arises in grub.

Following is the Slackware part from grub:-

menuentry "Linux (on /dev/sdc3)" --class gnu-linux --class gnu --class os {
insmod part_msdos
insmod ext2
set root='(hd2,msdos3)'
search --no-floppy --fs-uuid --set=root f8343290-7a16-43bf-8cfb-dec9e6cd62d6
linux /boot/vmlinuz root=/dev/sdb3 ro vt.default_utf8=0 vga = normal
}

Thanks

Add "rootdelay=30" to the kernel parameters.
