[Openchrome-devel] 答复: 答复: [Bug 92711] Unknown Card-Ids (3371|1019|2125)

[黄然]

Hi Kevin,

	Thanks, as I wrote in previous mail yesterday. This issue has been solved and latest UMS driver can work on VGA port with my board.
	Right now, I have compiled the drm kernel and bootup with that kernel. An AGP error bug is reported in dmesg, so I reported in Bugzilla:
		https://bugs.freedesktop.org/show_bug.cgi?id=94473
	Not sure if anybody has met the same issue before. Next step, I'll setup the debug env and see what happens in DRM code.	

Thanks,
Frank
