Can someone tell me under which condition the top command would return negative values ?
Is there a known bug w.r.t top command ? if yes do we have patches ?
Not really full answers here. The distribution and machine specs might have been helpful. Machine specs especially given my concerns about 64-bit and 32-bit discrepancies as well as JeremyBoden's observation:

So,
2.6.32 kernel dates back to 2009, however that is the correct procps version to go with that kernel. And that version went EOL last year https://lkml.org/lkml/2016/3/12/78.
Either case, I believe 2.6 kernels came in two release forms, 64-bit or 32-bit. 64-bit on a 32-bit machine may be fine. And I'm thinking that 32-bit on a 64-bit machine may be fine, but there may be oddities which you're seeing here.
I do not see any top() bugs cited.
Once again, machine specs may help here. To really debug this better, someone would likely have to take the time to compile procps 3.2.7 from source, with the debug flag, and debug top() when you run it.
