I typically on keep snapshots around for a while on kernel version bumps and some recent ones to fall back to, so have a blind spot between 5/15 and 5/30. We already know that the 7f47* version doesn't work, but I also tested with the 6f7b* version and that didn't fix the issue. -- You are receiving this mail because: You are the assignee for the bug.
