No problem. I'd like to fix this as much as you would, since the STA
driver isn't an option here. Just for kicks, I tried STA after this but
it didn't work with the wireless extensions on my system and I much
prefer getting the staging driver fixed. Meanwhile, I have no WiFi on my
shiny new netbook, so I'm very keen to help get this fixed :)

Can you do me three favors:

1). Tell me what kind of hardware you are testing on that's 32-bit?
2). How many CPUs (threads, cores, whatever) do you have?
3). Share your test kernel configuration?

It's likely that we could have a combination of different config (I have
every debug option turned on pretty much) and different word size and
I'd love to have that data. I will look through the crash tonight.

We need data points on 64-bit kernels. Anyone else care you share?

Sorry. I don't have a suitable test environment with this hardware (it
took several hours to get to the disk and swap it out the other night
since ASUS really don't want me to do that) but I suppose I might try a
nightly rawhide 32-bit compose on a USB stick and built the driver
against that - hmm. That might be a nice way to test 32-bit.

Yea. What about the high order bits in the phy msglevel, what are they
intended to be doing? Could you, perhaps, give us some more useful docs
to accompany what is in the staging tree at this point?

Thanks,

Jon.
