I'm using a 6950 (not CAICOS) and it was working great with commit <a href="http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=81ee8fb6b52ec69eeed37fe7943446af1dccecc5">http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=81ee8fb6b52ec69eeed37fe7943446af1dccecc5</a> for my Cayman (but not for CAICOS according to reporter of <a class="bz_bug_link bz_status_REOPENED " title="REOPENED --- - Radeon HD 6450 (NI CAICOS) screen corruption on boot" href="show_bug.cgi?id=42373">bug 42373</a>) 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 <a class="bz_bug_link bz_status_ASSIGNED " title="ASSIGNED --- - [KMS][Cayman] Garbled screen and oops with 6950 with linus git from 20121006 (3.7-rc0)" href="show_bug.cgi?id=55692">bug 55692</a> 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.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
