Has anyone with a Thinkpad 600e been able to run it with the 2.6.- kernel?

I've been messing with Knoppix and Mepis, both of which have options for loading this kernel and a stable 2.4.26. Both load fine when I choose the 2.4.26 kernel but I get the following when attempting to use the experimental 2.6.:

'Unable to handle kernel NULL pointer dereference at virtual address 0000000C.
(prints out lots of numbers here)
Kernel Panic : Attempted to kill init!

Then the machine does a hard lockup.

I realize this is an experimental kernel but I hate to think that my laptop won't be able to run future releases with a 2.6.- version.

BTW same said kernel runs great on my desktop.

Just wondering.

Don't worry about future releases not working on your laptop, you'll figure it out eventually. Do you get any clues concerning which process might have caused this error? I have googled for the error you talk about, and it looks like within the number and junk below the "...dereference..." portion of the error there might be some clues, can you post that? Where does this error ocurr, at boot time? After most things have loaded? Does the kernel load at all? Which release of 2.6 are you trying? I know these are only questions, but we gotta start somewhere.

Mike.

Thanks for the reply.

Kernel version is 2.6.4.

Stops loading after the cd-rom (hdc) has been detected.

That's the message, then lockup.

Clues??

when you compiled this kernel you remembered to move the system.map over right?

Mike.

I think I know what it is. Are you using hdc=ide-scsi for your kernel? With 2.6 you no longer need to do that. Check the docs in the src tree and you'll see what I mean. Check your lilo/grub config to see if that parameter is set, disable it, and reboot to see what happens.

HTH
Mike.

There's no kernel recompiling going on...these are booting from 'live' CD's. However I do believe I can feed it some parameters and I'll try no scsi and see what happens.

Thanks.

I have been running the 2.6 series on my 600E since the pre-releases and I have no problems at all.

One thing you may want to look into is upgrading your Thinkpad's BIOS since older revisions had a bug that made it virtually impossible to boot Linux at all. I am running the latest available BIOS from the IBM website and it works very well.

I do use ide-scsi though. It helps a lot when you're ripping audio CD's, so ide-scsi isn't completely useless.

Tried running it with no scsi but that didnt' solve my problem. I still get the same error message.

Hw-tph, I haven't had any issues with the bios in the past, but I'll keep your suggestion in mind. For the time being I'm gonna stick with the 2.4. series kernel.
