Ok, I'll try that.

FYI, I tried a few different kernels.  So far, this is what
I've found (I'm using source from a local CVS repo since it's
easier than having to be online all the time):

   cvs -d /opt/FreeBSD/cvs checkout -D "15 Mar 2011" src
     Works (ath0 loads)

   cvs -R update -P -d -A -D "22 Mar 2011" sys
     Works (ath0 loads)

   cvs -R update -P -d -A -D "1 Apr 2011" sys
     kernel panics

   cvs -R update -P -d -A -D "10 Apr 2011" sys
     kernel panics

   cvs -R update -P -d -A -D "14 Apr 2011" sys
     kernel panics

   cvs -R update -P -d -A -D "15 Apr 2011" sys
     kernel panics

   cvs -R update -P -d -A -D "15 May 2011" sys
     Fails (kernel works, ath0 doesn't load)

I have not had the chance to find the exact endpoints of
where the kernel panics, and to test ath outside of
those endpoints.  But somewhere between March 22 and
May 15 ath stopped working.

I don't have traceback for the panics, but I believe it
was cardbus related.
