Wish that would happen with me too :)

You need to work out how this does not happen for you.  What version of
GDB you're using, which you've never said.  What other confounding
factors, like kernel patches, may be involved.

I've tried with nonpatched 2.6.x kernels, although I can't remember the exact versions. Currently I'm running 2.6.9-rc2-mm1-VP-S1 (VP-S1 = voluntary re-emption). I've tried with Debian's gdb v6.1-3 as well as sourced compiled gdb v6.2.1

I can give access to the computer if it helps (sending in separate mail).
