The problematic condition causing the whole ring to be claimed dead is

     I915_READ_HEAD(ring) & HEAD_ADDR) == 8

right?

I915_READ_HEAD(ring) returns 000e200c HEAD_ADDR is 0x001FFFFC, so the result is e200c, not the expected value of 8, causing the ring initialization failure.

Or am I completely wrong here?
