call trace?


I run a 24/7 server on my Slackware 10.2 box. It was running kernel 2.6.13 kernel for 3 months. This weekend I realized that when it boots it would boot normally and then a weird message went by that said:

call trace

and had a bunch of strange numbers below it. I didn't used to get this and it worried me. I compiled kernel 2.4.32 and now when I boot with that kernel I don't get the funny start up message.

Anybody know what that means?

What appeared right before it in log? I guess some program crashed on startup, leaving inner function call trace. It is information inner to program (and useful for debugging/bug reporting sometimes), but it can be interesting for you which program crashed. Or ignore it - if you are OK with 2.4... For some time, until you will upgrade..

My wireless NIC module is kernel specific and I had to uninstall it from the 2.6.13 kernel in order to get it to work in the 2.4.32 kernel. I was also worried that somebody had cracked into my server and made it into a sleeping zombie-that kernel has no NIC now...anyway, I will boot into the 2.6.13 kernel when I get home and post the relevant part of dmesg.

ok, here's a snippet from dmesg in kernel 2.6.13 with a message about Call Trace which doesn't appear in dmesg in kernel 2.4.32:

It is a kernel bug, as the heading indicates.
