I've been playing a bit (booting and restarting with kernel 3.7-rc1) and strangely, what I see is very similar to what I was observing in bug 43655. It was then merged with bug 42373. At the time, attachment 64759 [details] [review] [review] was proposed and a similar patch ended up being commited that fixed bug 43655 for me (but it never fixed bug 42373 on NI CAICOS).
I'll try the workaround used at the time to see if it is really related to bug 43655 (comments 8 and 10) and I'll begin bisecting kernel right after.
I think what you really want for your caicos is this patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit; h=62444b7462a2b98bc78d68736c03a7c4e66ba7e2
You misunderstood me. I'm using a 6950 (not CAICOS) and it was working great with commit http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=... for my Cayman (but not for CAICOS according to reporter of bug 42373) included in kernel 3.6. What I'm saying is that the symptoms I'm now seeing with 3.7-rc1 are similar to what I was seeing at the time, but it was fixed in 3.6.
Now, about the patch you propose, it is already included in kernel 3.7-rc1 according to commit history. Since I'm experiencing bug 55692 with 3.7-rc1, the proposed patch can't be the cure. I'm bisecting right now between kernel 3.6 and 3.7-rc1. If it appears to be a different bug than 55692, I'll open a new one.
