SMP Frequent Lockups

Hello,

I am having issues with my WPC11 Linksys PCI card and a 2.4.21 SMP kernel. I recently upgraded the machine with another processor and recompiled the kernel to support SMP. Previously ive had only 1 or 2 lockups (non SMP kernel) using Hostap 0.0.3 under heavy traffic (FTP for instance) over a 3 month span. Now with the SMP kernel I have lockups with even light usage of the wireless AP (ssh or webbrowsing). These are hard lockups that require cycling the power via unplugging. I can verify that the lockups only happen with some sort of traffic on the wireless card, as I can keep the hostap module loaded with the interface down, and not crash. Anyone have a solution? 

Ive tried every patch I can get my hands on, as well as the Hostap CVS code.

I will have quite a bit of free time from now until Aug 25th or so, and I am willing to test any patches / ideas thrown my way ;)
