Kernel 2.2.19pre7 runs fine Kernel 2.4.0 runs fine Tested kernels that didn't work 2.4.1, 2.4.5, 2.4.6, 2.4.7, 2.4.8 ,2.4.9, 2.4.9-acx, 2.4.9-prex, 2.4.10-ac11 So I asume something changed between 2.4.0 and 2.4.1, so I tried copying back smp.c and smpboot.c and then make clean dep bzImage etc Which didn't work. I always get the output below, I also include /proc/cpuinfo. I am not able to find the pre patches between 2.4.0 and 2.4.1 to narrow it further down. The way I look at the output is that the kernel only looks what the specs of the first cpu are and asumes that the second is the same. But what do I know. I cannot change procs since the second one's cooler is too big. Also running uniprocessor works ok with the latest kernels. I would really appreciate some help on getting any further on this.
