Can you please resend. Downloadable from http://sucs.org/~sits/test/eeepc-900/dmesg-20140611 . By the way, Mutt seems to be becoming upset when I group reply to your mails.

Alas, no :( Can you please add drm.debug=0xe to your kernel cmdline, reproduce the issue and attach the entire dmesg? Please make sure it contains everything since boot-up so that we can reconstruct the state properly (might need to grab it from logfiles if dmesg is cut off). Also, do you have any ideas when you reproduce this?
