This kernel seems to work well with my gm45, even with normal command line. Is this kernel stable? Is there any plan to provide a repository with GM45-compatible kernels like this one? -- [gm45] Screen shows corruption that blink once and for a fraction of second and then disappear (Needs

Yep, I forgot mentioning that it always appears in bottom of screen. It often look like horizontal lines, but sometimes it looks like a stripe of randomly colored pixels. Furthermore, it seems to not occur while running a fullscreen app. I apologize if the bug were already reported. -- [gm45]
