WP4758. Rolf, Jim and Dave.

We upgraded the following models to branch2.9: h1iopsusauxey, h1susauxey and h1iopsusauxex.

After h1iopsusauxey was upgraded, I did see the ADC error bit in the STATEWORD get set three times in the first 30 minutes. The enhanced ADC diagnostics Rolf put into the /proc status file showed the ADC0 READTIME MAX did exceed the 17uS limit (went to 18 each time). Unfortunately no addition errors were seen for the next 3 hours. We tried the same test on IOP EX, but that did not exhibit the error at all.

So it seems the ADC error is in 2.9 at EY, but is very intermittent. 

I reverted both IOP and user models on h1susaux[ex,ey] back to RCG2.8.4 and concluded the test.
