Image defects with 2.6.14/atyfb/Sunblade 100
[Forwarding information to linux-fbdev-devel]
Hello,
Recently Luigi Gangitano has pointed out a linux-fbdev-devel thread [0]
in which progress was achieved in fixing the atyfb bug resulting in
console and X display corruption on SunBlade 100, filed as #321200 in the
Debian bug tracking system [1]. The patch mentioned in the thread (which
we plan to include in the next Debian kernel package release) is attached.
While the situation with this patch is greatly improved, users testing the
new 2.6.14 kernel packages have reported [2,3] that there is still some
minor screen corruption in a form of red dots or lines. A screenshot
(provided by Andrey Chernomyrdin) can be viewed at [4]. We'd appreciate
any ideas which could lead to the resolution of this problem.
Please CC the responses to me (and, optionally to the
debian-sparc@lists.debian.org), as I'm not subscribed to this list.
