The weird thing here is that number: 2147483647
It is 0xefffffff
Which means -1 without the highest bit (the sign).
I really don't know how it could have happened.

Anyway, I caught something in the signedness bits from my patch that unifies
the format decoding.
I've never seen your bug on my machine. But I note you have a 32 bits CPU.
Mine is 64 bits with a 64 bits kernel. Perhaps some weird signedness related things
happened because of the signedness bug that the following patch fixes.

Since there are no negative values in my dmesg, I did not catch this bug until now
(and my top output is normal).

Can you please give it a try?

Thanks a lot!
