Hi Dear all, I am using uClinux Kernel 2.4.X on coldfire (MCF5485) CPU. I am facing following problem. Please help me.
Whenever I am transmitting packet of size greater than 962 bytes using UDP broadcast it displays following error & CPU halts. Kernel BUG at slab.c 1172! Kernel Panic : BUG!

As far as I know none of that was carried forward to 2.6.x kernels, so I would say there is zero chance it will work on any modern 2.6.
