For the record, I'm running a Debian kernel 2.6.24-6, or 2.6.23-1~mtu1
on a Intel(R) Core(TM)2 Duo CPU     E6550

(According to its changelog, 2.6.24-6 seems to be a 2.6.24.4)

So I might be using a too old kernel to reproduce the bug, or it does not
occur on dual cores.


Are you using a Debian kernel? Or an home-compiled kernel?

If instead of receiving answers by email, I receive computer to reproduce
this bug, I will share with you ;)
