Hi, Has anyone seen this: (or has any ideas?) I have an old Compaq - 486DX2-66 with 16MB ram which has been running SuSE 6.1 for about 8 months as a gateway/router. I want to upgrade (reinstall) to SuSE 7.2, but when booting from the SuSE 7.2 bootdisk (standard, or i386), I get the boot: prompt - followed by 'loading initrd' - followed by 'loading linux' - but then, after the 'uncompressing linux' message, I immediately get the following error message: Unable to handle kernel NULL pointer dereference at virtual address 00000000 Followed by a register and stack dump, followed by: Kernel panic: Attempted to kill the idle task! In idle task - not syncing I should emphasise that the same boot disk sucessfully boots on a variety of other computers. I'm really stuck with this one! Thanks Tony

What's the memory on variety of other computers? And what kind of installation do you select? Your problem is with low memory on that machine for YaST2 install. YaST2 install requires 64 MB RAM, graphical YaST1 install requires 32 MB RAM, text YaST1 install requires 16 MB RAM To get into text YaST1 install mode type manual at boot: prompt when you boot from bootdisk.

Hi Kastus, 'manual' - same error occurs. 'variety' have 32MB and up - but note this same PC was installed (and is running) with SuSE 6.1 YaST (0.9??) some time back. But we are not getting as far as YaST. It's bombing out right at the start of the boot kernel - and 16MB should be more than enough to hold the boot kernel yes? Any other ideas?

It's bombing out on intird, not on kernel. As you may guess, initial RAM disk has grown up since 6.1 times... and it does not want to fit in 16 MB. Actually, the specs on the box say 16 MB for text YaST1 install. Are you booting from floppy or from CD? I am afraid that wrong initrd is being picked up and it does not fit in memory. You may also try to use i386 floppy, you need to copy it onto floppy from disks directory on CD1.
Any other ideas?
I just looked at syslinux.cfg file on boot floppy. All labels specify a 64M ramdisk. I don't know if it would work, but try changing this value to 16384 for manual label. -Kastus

Hi Kastus, OK, problem solved by: boot: linux text expert mem=16M and we now boot up ok (from fd0 - the PC has no CD so it's an NFS install from now on). BTW, initrd still loads a kernel (into RAM disk!) and then unloads initrd and frees up the memory ;-) Thanks for the help - you pointed me in the right direction.
