aurelien, chances are the dbgsym was not actually a match for the running kernel
13:25
<
fche >
debian kernels sometimes reuse a lot of version/release numbers across rebuilds
13:28
<
aurelien >
but it does not produce that on the hello.stp test
13:33
<
fche >
some stap scripts don't require kernel debuginfo at all
13:33
<
fche >
so don't bother check for such version numbers

you are right, I have change the kernel version and it just works like a charm
14:03
<
aurelien >
thanks fche
14:04
<
fche >
np, it's unfortunate debian makes this harder than it need be
14:04
<
fche >
hoping that our elfutils debuginfod effort will be adopted in some form there so it can be all automated properly
