Machine Check Excpetion

I have a problem with my old Compaq LTE5280 Laptop. I was running Suse 7.1 with the 2.4 pentium kernel. After upgrading to 7.3 with the new 2.4 kernel I can't boot anymore. I get the following error: CPU#0: Machine Check Excpetion: 0x 28BA0C (type 0x D) I tried also the 486 kernel without any success. What is wrong ? Thanks Markus
