I checked into this some more and debian have a patched version that actually gets it right and it did not take the symbols from the System.map link. It was easy to check as that mapfile don't even have the "__mon_yday" symbol so it must have got the symbols from another file and unless it's seriously broken it should have picked the right one. So it lookes like the call trace was wrong and not the map file. I have now put "-k /boot/System.map-$(uname -r)" as argument to klogd so it can't possibly choose the wrong file but is there some reason to turn off the lookup in klogd and use ksymoops ?? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
