What happens is. I press home for the usb networking. I then telnet to tablet, can do the usual, dmesg, etc... then I press Menu key and get back to the boot selector. I still can dmesg, etc... if I select the flash as a booting option, then it works until the desktop loads when the usb storage kicks in (which was always like that anyway) but if I select the mmc2 as a booting option I get kicked out of telnet straight away. I do not even get the blue bar indicator just message on the top of the screen about booting from immc2 etc... then after about 5 sec the tablet resets (no dsme related led flashing)
and I am presented with the boot menu again. Strangely, after such reset I am unable to boot from flash as well and the unit simply switches off mid boot. When I do the clean start (battery out then in) then the n800 will boot from the flash without problems.
