Acer Aspire Z5600 Kernel panic

[fballem]

I have acquired a brand new Acer Aspire AZ5600 all-in-one computer. I have installed ubuntu 10.04 on the system - single boot.

When I restart, I am getting the message [0.681800] Kernel panic - not syncing: VFS : Unable to mount root fs on unknown-block(0,0)

I have wiped the disk using DiskPart from Windows. I admit that my technical knowledge at this point is very limited, so I would appreciate any suggestions that others might care to offer.

This really shouldn't be this hard!

Thanks,

prepare your hdd first:

kernel panic can happen from many reasons, but always use the distro tools to work on a specific distro (dont mix windoz tools with ubuntu tools

as your pc is a recent model you probably find some unknown issue: look at errors logged (system admin logviewer) and google around the chipset giving trouble

Thanks - I downloaded PartedMagic.

I am still having the exact same error message however. There seems to be a block at the start of the disk that I cannot get rid of.

When I run fdisk -l from Parted after installing ubuntu, I get the following information:

/dev/sda1 start 2048 End 1917845503 blocks 958921728 id 83 sytem Linux Boot *

/dev/sda2 start 1917847550 end 1953523711 blocks 17838081 id 5 system Extended

/dev/sda5 start 1917847552 end 1953523711 blocks 17838080 id 82 system Linux swap / Solaris

I have a feeling that I have to configure Grub - but I am not sure what values I need to put into the Root or the Setup parts

Thanks,

I tried installing Ubuntu 10.10 Alpha 3 using the Alternate CD. I still have the kernel panic error, but I do have a little more information to go with it:

I hope this helps

Hi. I had the same problem (with the same computer). After quite a struggle here is how i fixed it :

- restart and go to the bios
- go to the menu advanced>Advanced Chipset Feature
- switch "Memory Hole Remapping" to disable

I don't know what it is, but it seemed to fix the problem.

Perfect - it is now working!!!!!

After searching and searching, digging, sweating, swearing, threatening to go back to *******, installing, reinstalling, 9.10, 10.04, 10.10, with a clean install each time, and the Kernel Panic to follow - I happened upon this thread.

I'm running a Frankenstiened desktop, but the memory hole fix worked a treat for me. Thanks a million!!! :p
