 kernel 2.4.2 SMP + ATM hangs

Hi there!

We are having problems with a Compaq Proliant 1600 Server and a Fore 200E
ATM card using kernel 2.4.2.
We have been using it for a long time with SMP enabled and everything
worked just fine (we didn't have ATM).
A couple days ago we installed a Fore 200E ATM card and after getting the
ATM address using ilmid the machine hangs. The kernel still respond to
pings, but the userspace is dead.

If we remove SMP support in the kernel everything works fine (but with
only one CPU)...

Salu2!

 kernel 2.4.2 SMP + ATM hangs

You probably need the patch that Chas Williams came up with in January.
I've been meaning to forward it, but I haven't yet.  Please try it and
see if it fixes your problem.
