I'm assuming you are talking about the LFS liveCD.

- Which version are you using?

- Is this a normal boot or done from a virtual machine?

Can you post the lines shown before the Kernel panic - not syncing:.... line? Those lines probably give an idea where things went wrong.

Yes I am talking about LFS live CD -x86-6.3-r2160-min.
It is a normal boot from CD.

these are the lines I see before Kernel Panic line:

Even if you dont know the solution please help me how to read the above message. But please try to solve as I have to do a project on LFS and I am unable to even boot, forget about doing whole project.

Thankyou

Hi,

I'll have a better look at this once I get home (working now....).

Only possible fast solution: Try one of the other liveCD versions

druuna 05-10-2011 11:26 AM

Hi again,

There's not much to go on when I look at the code snippet you posted (if there is more, please post it).

I suspect this has something to do with TSC (clock source), but I cannot point you to anything specific.

This could be caused by:

- a BIOS setting,
- incompatible/very new hardware,
- kernel setting.

I would check the BIOS and see if all is correct, no harm in checking.

Searching the net the closest I came was this one: motherboard with Q9300 CPU does not boot SMP It cannot hurt to try the idle=poll suggestion (but reading the article I wonder if it is a solution).

Trying to debug this option might be hard to do, I would try one of the other LFS liveCD's. I never had any problems with the r2145 version (both x86 and x86_64).

I noticed you posted this issue to the lfs mailing list, maybe someone of them has seen this error before.

Hope this helps.

What should I do ?

I meet this issue too.
My platform: WIN7 64, VMware v7.1,

I tried install Ubuntu 14 and Fedora 20, both meet this issue. After I use VMware 10.0.2, This issue is gone.
So I think it should be VMware issue.
