>>I have also reported this problem a few weeks ago.  I have a HP Pavilion zv5340us laptop with Broadcom 54g card.  In my case, all worked fine with 500MB of memory (2x256MB memory modules), but I got the 100%CPU usage issue when I replaced one 256MB module with a 1GB memory module.  I've even tried moving the 1GB module to the 2nd memory slot (requires some dis/reassembly of the laptop to get to it under the keyboard).

>>You mentioned that you think its a problem with the driver itself.  That may be a possibility, as I expect the 64-bit Broadcom driver to be in some sort of pre-release state.  And HP likely modifies the driver for its use.  For example, there's a lighted button above my keyboard to turn the wireless feature on and off.  In 32-bit windows using drivers provided by HP, the light is on constant when the wireless device is on.  In 64-bit windows with the same driver we're using in driverloader, the light only flickers as data is being tranmitted/received.  I suspect (hope) HP will modify this once they officially support 64-bit Windows to have the light stay on constant when the wireless feature is on.

>>In any case, there are other indications that the problem may not be in the driver.  Under earlier versions of the linux kernel (2.6.8-24.11 - from updated SuSE 9.1), my system would lockup completely instead of just hogging the CPU.  I had to hard cycle the laptop to recover.  In addition, the driver works fine under 64-bit Windows (the latest beta version available at M$ website) with all of my different memory configs.
>>
>>I was originally thinking the issue might have something to do with unequal memory modules in the 2 memory slots and some interaction between the linux kernel and the memory hardware/controller.  However, if you've got 2GB of memory, I assume you have equal (1GB each) memory modules in the 2 slots.

>>Since the behavior is different between linux kernel versions <= 2.6.8-24.11 vs. >= 2.6.10xxx, at least part of the problem may lie with the kernel itself.  There could even be some hardware issues (timing, BIOS, etc) involved.
