Hiya, So mips on the atheros 24kc and 74kc parts is just completely borked. It varies between "this doesn't even boot" to "all I get are spams of failure exceptions", and if i back out a variety of hilarity, i end up with a userland that just plainly hangs after userland runs for a little while. No CTRL-T, nothing obvious in ddb. But hey, 'cont' in ddb now works. The working release for me is 304552, which is when I finished updating the atheros config files to use std.XXXX instead of ARXXXX_BASE. It's going to take some time to find the first point where things broke. It's likely going to be a combination of everyone's recent mips platform changes (most of the exceptions, the not-booting-at-all) and other unrelated kernel changes to other areas (likely the hang.) I ask that people hold off on the MIPS side of work until I figure out what's going on here. Also - I really do suggest you invest $40 in a carambola 2 so you have the AR9331 as a reference platform to do MIPS testing on. These mips24kc, FPU-less cut down SoCs are in a lot of things and having now heavily broken support for them is kinda sad. :( It's also putting a cramp on my ability to finish my net80211 and 11ac changes as a whole lot of it depends upon working AP hardware to test against. Thanks, -adrian
