Re: Kernel panic: VFS: Unable to mount root fs...
I went through make config again while reading the Configure help file for the source (along with making the image and the other processes), and, upon boot, the new kernel got as far as VFS: root fs mounted [...] then it simply stopped. ...anyone have any info that would help here? Does the Debian system need to have kernels made differently from other Linux kernels (e.g., directory differences?)?

After make config, make dep, make zImage, make modules, make modules_install and lilo (and copying zImage to / as vmlinuz), I rebooted the machine. It booted partially, then stopped with the error message Kernel panic: VFS: Unable to mount root fs on 03:02. Can you help me get past this one (first time compiling a kernel)?

You did compile in (not as module) the IDE driver right? And support for the ext2 filesystem? Looks like missing IDE support was my problem. I had read only the beginning of the help on the Enhanced IDE support: ... the full-featured IDE driver to control up to four IDE interfaces ... and had figured that, since I have only two IDE drives, I did not need this full-featured driver. If I had read further: ... If you have one or more IDE drives, say Y ... I could have spared us this thread. Well, problem solved, and thanks for your help. Lesson learned: R(all)TFM. Matt Miller

The first few trys seemed to work, (removing PCI support, setting processor type to 486, etc...), but now, no matter how simple of a kernel I try to build, the system won't reboot. The kernel loads, then, after about 3/4 of a screen of normal startup messages, the system halts with: VFS: Can't open root device 03:01 Kernel Panic: VFS unable to mount root fs on 03:01 You might be making your kernel too simple if you don't include support for the minix fs then it cannot mount the root partiton. Try remaking your kernel and be sure to include ext2 support. What do these messages mean, what have I done to myself, and how can I undo it? Next time also try to use the kpkg utility, all you do is enter the source directory enter kpkg and it creates a .deb of the kernel (well almost you'll have to read the doc's or ask me for more info if you want it).

VFS: Can't open root device 03:01 Kernel Panic: VFS unable to mount root fs on 03:01 strange maybe you compiled the root fs as a module (which is not to be done), but how would you boot?... ah there's the answer: I installed the 2.0.34 kernel source package. I think I'm following the instructions in /usr/doc/kernel-source-2.0.34/README. I do: make mrproper make menuconfig make dep make clean make zImage make modules make modules_install cp /usr/src/linux/arch/i386/boot/zImage /boot/vmlinuz-2.0.34 lilo dear mister, that's the orginal doc from de kernel source, not the Debianized one. well, with Debian there are some more files that are necessary for the kernel to work (e.g. : /boot/SystemMap) you have to use the make-kernel package tools, or whatever is its name : # cd /usr/src/linux # make-kpkg clean # make xconfig /* sorry I like it :) */ # make-kpkg -r custom.1.0 binary which buils all you need in /usr/src then # cd /usr/src # dpkg -BRGiE kernel-image 2.0.34_custom.1.0.deb but before : $ man make-kpkg $ cd /usr/doc/kernel-(uh what's its name? look for it!) and rtfd :) you're welcome -- Samuel Landau

I have never used the Debian style and always installed my own kernels. /boot/System.map is not essential for the boot process either. Remember.. Debian is just Linux .. there's nothing special about the kernel. Mike. -- Did I ever tell you about the illusion of free will? -- Sheriff Lucas Buck, ultimate BOFH.
