Problems with an0 and 5.2-RC1,BETA

Hi,

I've been having some problems with my an0 device and 5.2-RC1,BETA.  5.1-RELEASE
worked great.

I am able to get an IP from my AP's dhcp server, and sometimes I can transfer
some data.  However it seems that at random my system freezes up partially.

I get:

an0: failed to allocate TX descriptor
BUSY
an0: failed to read RID ff50 0 0 0 0, 3
BUSY
...repeated very slowly.

For all I know it could just be my keyboard that's being frozen.  I had my lid
light on, and I wasn't even able to turn it off.

My guess is I have some interrupt related problems, as I've had them in the past
with my fxp0 device, but I haven't been able to figure out how to logically
solve the problems.  I thought I'd better post just incase... I'd also like 5.2
to be a great release!


Here's some information:

vmstat output:

%vmstat -i

Total                             673361        392

I'd like to know how to read this, but the manpage didn't seem to help me much.

The device:
