Hi,
I have a problem with kernel 2.3.99-pre5. I get always a kernel Oops
like this one for example:
Unable to handle kernel NULL pointer dereference at virtual address 00000000
printing eip:
00000000
*pde = 00000000
Oops: 0000

Code: Bad EIP value.
What I have done:
I have created a bootdisk with syslinux-1.48 containing a bzImage, a
initrd image and a syslinux configuration file:
Directory for A:/
ldlinux sys 5860 04-22-2000 16:12
initrd gz 341732 04-22-2000 23:54
syslinux cfg 90 04-22-2000 23:58
linux 510866 04-22-2000 22:58
The file syslinux.cfg contains the following append line:
append initrd=initrd.gz root=/dev/ram init=/linuxrc.bash console=ttyS0,9600 console=tty0
The initrd image contains the three programs rc-1.5 (the Plan9 shell),
bash-2.04 (--enable-minimal-config) and busybox-0.43. The file
/linuxrc.bash is a simple script:
#! /bin/bash
/bin/bash -i
It does not matter whether I run bash or rc. The system boots fine
and starts the shell and I get the prompt (# or ;). But when I type
in a command like ls for example, I get the Oops at once.
The kernel contains only the romfs and devfs and most network options
(netfilter) but no other filesystems and no NIC driver and no SCSI, no
ISDN, no frame buffer, no video, no etc. but EIDE and the serial
console code. But it makes no difference, when I disable the serial
console. I don't know if it is usefull, when I post the startup
messages or the kernel configuration. I don't know how to use
ksymoops, because my working system has only a 2.0.38 kernel. The
systems runs in Vmware 1.1 on Linux 2.0.38. I have compiled the
kernel with gcc version 2.95.2.
I have no idea how to make this installation any more simpler.
What goes wrong? What can I do?
