This is during boot up:
It has grabbed the kernel, and initrd if you specified one. Next thing it does is mount / ro - all before init is started.

It can't find /. Causes: Wrong drive specified, pathname error, unable to read filesystem, i/o error, that sort of thing

raleeha · 04-20-2011, 07:54 AM

maybe this caused by diffrent names.../dev/hda2 (VL6.0).../dev/sda2 (VL7.0)...tried to change lilo.conf but there are no results

Double check that your kernel can read trhe root filesystem. It has to be compiled in, or in an initrd. A module isn't enough; it lands you in catch-22 - you need the module to read the filesystem the module is on.

Then you have the root drive specified wrong. root=/dev/??? on the boot line. Modern kernels should have /dev/sda, etc.

vl 6.0 uses kernel 2.6.27.12 and vl 7.0 kernel 2.6.38

wonder why the /proc dir is empty

the problem bootloader lilo uses *h*da in vl 6.0 and *s*da in vl7.0...so probably i need to change the lilo.conf file on vl 7.0 with the content of lilo.conf vl 6.0..but i dont know if vl 7.0 already will work then

Because it's a backdoor to ram.
