I have an IBM Thinkpad T22. I tried to add a 256mb stick and now when linux boots it quits on me with a kernel panic. Anyone have any ideas?

Note: I'm using IBM (samsung) ram that was previously in a T23, so I don't think its the RAM.

You might have the wrong ram.

Is windows available? Does it boot?

Can you boot into a console and look at dmesg?

Windows is not available on my machine. However, It booted on another T22 with windows.

kind of lame suggestion here, but are you sure you're seating the ram properly? what happens if you take a stick of ram from the ibm laptop running windows and put it on your ibm laptop? just grasping at straws here.

Yup it's seated fine. The bios reports the correct amount of RAM.

I'm beginning second guess myself though. I switched my laptop back to "normal" boot (was in quick mode) and had it do an extended memory test. Things get all whacky when I do this. At some times it only sees 64mb of the 384, which is just weird. Others it will see it all. Maybe it is a sketchy module. If it is thats going to suck, because I really have no idea which ram to buy now. This ram is was shipped from IBM and is used in the thinkpads....if it doesn't work properly what will??!

well, i always look for ram at either crucial or kingston. both have things where you can input the model of your computer/laptop and it will list the available ram models that are guaranteed to work with that model computer.

you may want to give them a try. another question, do you think there's any bios updates for you laptop?

Checked both stores. I was originally going to go with Crucial, but they only have 128mb dimms for my machine. Kingston seems a bit pricey to me.

Yes, there is a bios update for my machine. I tried the RAM before and after the update, still no go. Very frustrating. There's nothing like spending money on something you can't use.
