Therefore the jsr should have jumped to the address in t12 which is 0000000002969588. t12 gets loaded from s0 in the previous step. I was unable to trace back the memory address content, is there a way to do it? The last function in the trace is given in the following link: > http://lxr.free-electrons.com/source/net/core/neighbour.c?v=2.6.28#L1187 [1] > Could someone suggest how I go about debugging this kernel panic? Thanks in advance.. > Thanks, > Pritha You'll need to either use the gdb support in gem5 or maybe put some checks in the memory system for that specific address and print as it gets changed.
