Hi, excelent! The amd64 seems to be working, I don't have the "drm" error (see here). HOWEVER the rt2800 is still on (see below). As for the freezing of keyboard and touchpad, I couldn't reproduce it voluntarily in the past, and it didn't occur yet.
Thanks for any other good advices. V. P.S. I rebooted and instantly suspended the laptop, then I woke it and after that I ran the terminal. $ dmesg | grep drm [ 1.397461] [drm] Initialized drm 1.1.0 20060810 [ 1.470191] [drm] MTRR allocation failed.
