Some months back I started playing with newer bootcode and dtb files on the RPI2, and rolled them back after running into serious problems with the unit not always progressing beyond the "ue0" device probe.=C2=A0 That= is, the unit would get to the "ue0" line, print it, and then lock up. ^C was ineffective on the console and sometimes - but not always - after a couple of minutes it would unlock.=C2=A0 The rest of the time, however,= you were dead unless you pulled power and restarted. This is back on 11.STABLE builds, and it appears to be linked to the roll-forward of the bootcode and DTB files that was somewhat-recently committed.=C2=A0 I was forced to go back to the older files. IMHO this needs some attention as a lockup during the device probe is a bad thing, obviously. --=20 Karl Denninger karl@denninger.net <mailto:karl@denninger.net> /The Market Ticker/ /[S/MIME encrypted
