This case Eric ran into should be already fixed by a patch from Jan that went in before 2.6.18 even. He just ran with an old kernel (2.6.18-rc3) that didn't have that particular fix. Still the kernel stack termination is probably a good idea. I think (haven't tested) the current 2.6.18-git* code with termination wouldn't have crashed, but reported a (incorrect) stuck. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
