Help is welcomed as I'm not going to look at it in the foreseeable future (I'm busy enough with other things).
(dri-devel@lists.freedesktop.org or linux-fbdev@vger.kernel.org) into CC?
Added to Cc:, thanks.
Hmm. There is something strange about it. I use vga console quite often, and scrolling happens all the time, yet I can't get the same out-of-bounds report (nor have I ever seen it in the past), even with the reproducer. Is it supposed to be executed as it is, or are there any preconditions? Any chance that something that runs prior to that reproducer somehow impacts the system? Just asking.
