Default Weird SMP problem

I swapped out my Sempron for an Athlon X2 4000+, but when I have
"Symmetric multi-processing support" enabled in the 2.6.24-hardened-r2
kernel, the system freezes as soon as the madwifi wireless interface
starts in master mode. Weird. Any ideas?

http://madwifi.org/ticket/1903

has the solution. Apparently it's a kernel bug, hitting a lot of people
and a workaround is to downgrade to madwifi-0.9.3.3

Thanks Alan. Compiling madwifi-ng-0.9.3.3 I get:

ARCH mismatch: supplied "x86", determined "x86_64".

It's covered here:

https://bugs.gentoo.org/show_bug.cgi?id=205116

and the solution seems to be upgrade to 0.9.4. Hmmm. I think my only
option is to disable SMP support until this is fixed.

'Tis indeed a sad state of affairs.

I'm also out of my depth here (never used madwifi), but what happens is
you downgrade to a version lower than 0.9.3.3?

Unless 0.9.4 is the first version to support amd64, in which case I'd
agree that you are out of luck.

That's a good idea and it might work but I've got a critical system
picking up the wireless signal a fair distance away. I'd rather not
jeopardize it and just let core #2 sleep for now. I guess I should
try again with another release of the kernel or madwifi.

Thanks again.
