Hello All,
I just compiled the latest kernel 2.6.16.11 from source and its created
a vmlinuz-2.6.16.11 file along with a link vmlinux in the /boot folder.
Since 'make bzImage' only creates a kernel image, the 'make install' was
used finally to get it into the boot folder for grub.
You'll need to do 'make modules_install' to install the new kernel modules too.
In grub's menu.lst, I configured the kernel as /boot/vmlinuz and
root=/dev/hdan where n is my partition and its the same entry as in my
existing kernel entry. The image entry is #shed as there was no img
created. When I boot into the new kernel, after a series of initial
text, it gives a kernel panic at the root= entry. Its the same as before
so why can't it mount the VFS on that partition? It cannot recognise
hdan. (n is a number)
Are you sure you compiled ide-disk into the kernel? If not and if the
earlier modules_install is also not done then its possible thatyour
disk is not found.
Also, you need to compile your primary filesystem driver into the
kernel. If your root filesystem is reiserfs for example then reiserfs
should be compiled into the kernel.
And then you have a different set of problems if you're using a
ramdisk (initrd).
You can still boot with your old kernel though. when faced with the
grub menu press 'c' to go into grub shell. The execute the following
commands (I've assumed you're using hda5 i.e. grub disk (hd0,4) and
your old kernel is vmlinuz 2.6.1):
--------------
# Specify the root partition
root (hd0,4)
# specify kernel location. TAB will give you an autocomplete list
kernel /boot/vmlinuz-2.6.1 root=/dev/hda5 ro
#boot the kernel
boot
--------------------
Again, if your distro uses initrd then before 'boot' you need to
specify the initrd image location with 'initrd <image location>'
Refer to the grub manual online to know more about the options.
