Re: kernel compile - Unable to mount root fs
This is a bug in the 2.6.30 source. The quick work-around for this is: update-initramfs -c -k "uname" "uname" being whatever you've named your custom kernel & do it without the quotations. Check to see if there is now an initrd-image file for your kernel in the / boot directory & if there is do an "update-grub" & you're good to go. ~Amax~ -- A person needs only two tools: WD-40 and duct tape.

Re: kernel compile - Unable to mount root fs
It only brings up this error message on a VirtualBox machine.. :D I tried to compile the vanillia kernel on two other machines, and it worked, booted without error.. :) The VirtualBox machine was only to try, how it works, thank you!

Re: kernel compile - Unable to mount root fs
mkinitrd is a standard command on all linux systems, so you can check its manual page. Maybe man update-initramfs can help too. Best of luck.

Re: kernel compile - Unable to mount root fs
In your Grub menu.lst file, there are some lines that look like this one: initrd /initrd.img-2.6.26-2-686 You need a line like that just below the item for the kernel you're trying to boot, except that you want the initrd version to match the new kernel version. initrd stands for Initial RAM Disk.

Re: kernel compile - Unable to mount root fs
Did you build and install your initrd? You might need to load a module to mount your root filesystem, and if so it should be in the initrd. The initrd also needs to be named in your grub entry. It's not enough just to build and install the module, because those are accessible only after your root fs is mounted! -- Don Quixote de la Mancha quix...@dulcineatech.com http://www.dulcineatech.com -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
