Hi,
I am currently running Debian Sarge testing.
GCC version is 3.3.4
I needed to compile and install 2.6.15
used
$make-kpkg kernel_image
$dpkg --install kernel-2.6.15*.deb
Now when I try reebooting into the new kernel, I get:
VFS: Cannot open root device "hdas" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
I see that the device entry for the default(working) kernel is the same.
The new root entry is made automatically when update-grub is run at
the end of 'dpkg'
I see that there is no initrd entry. Could that be the reason ?
Yes, that's probably the reason. See yesterday's thread "2.6 compilation
woes..."
My understanding is:
If you don't include the switch "--initrd" on your "make-kpkg" command
line then you *must* compile the drivers for your hard disks and the
filesystems you're using permanently into the kernel (ie choose compile
option "Y", not "M" for these drivers).
If you do include the switch "--initrd", then you can make modules out
of everything and the system will load everything appropriate for your
hardware during boot, which seems to me a rather nice way of finding out
what hardware you actually have in your machine.
