I have just updated the DreamPlug to kernel 3.11.5, without any problems, but also tried 3.12-rc5, with – as usual – no success..<\/p>\n

My DreamPlug – presumably one of the earlier models – is actually a ‘GuruPlug Reference Board<\/em><\/strong>‘ inside:<\/p>\n

This is the same as in the corresponding file in the 3.11 kernel source tree, but there seem to be no ‘guruplug’ options available in 3.12rc, apart from ~\/arch\/arm\/boot\/dts\/kirkwood-guruplug-server-plus.dts, which works when used to create the uImage in 3.11.x, but fails in 3.12-rc.<\/p>\n
I am running out of testing options, now, and unless I can find a reference to this issue, I might eventually post a question on the appropriate kernel mailing list..<\/p>\n
