This is the "just-set-256.diff", which has shown no issues in testing. However, I also thought it may be wanted to only set corbsize/rirbsize in the failure condition, and so I also made "keep-ifs.diff", which also works fine. Only one of these diffs is needed. I am open to refining further if need be. All credit is avg@'s. Thanks. -- You are receiving this mail because: You are the assignee for the bug.home | help
