CarlFK[m]what about --kernel ?00:39
tumbleweedit's an argument to flterm00:39
* tumbleweed is actually going to go home now, and can poke at an atlys too00:39
CarlFK[m]oh.. but mode swich should be doing that?00:39
tumbleweedmodeswitch doesn't know how to do that, as you can see00:40
CarlFK[m]well, it wasn't installed the first time00:40
CarlFK[m]but yeah, installed, same error00:40

CarlFK[m]I need to run to dinner for about an hour - any interst in sshing to my box?01:17
tumbleweedI mean, it boots, and video is borked01:18

* tumbleweed tries git bisection again. We have to dig into the nextgen branch...01:30
mithrotumbleweed: No guarantee you can the old nextgen stuff :-P02:26
CarlFK[m]mithro No guarantee  ... what?02:42
mithrocan build02:42
tumbleweedif it takes > 1hr: give up, right?02:55
CarlFK[m]tumbleweed (IRC): is the cpu spinning?02:56

CarlFK[m]I thought it went idle.  which made no sense.02:56
tumbleweedok03:01
tumbleweedI was suprised how fast the nextgen build was03:01

CarlFK[m]yup21:58
tumbleweedmithro: that basically means that the atlys has been broken since atlys support was added to nextgen22:16
mithroThat would have been my guess22:17
tumbleweed840e634e is only about 8 commits after atlys support was added22:17
tumbleweedand it built (earlier ones I tried didn't)22:17
tumbleweedso, I'm back to being interested about strategies in testing22:18
tumbleweeds/testing/debugging/22:19
xfxfDon’t update the gateware? ;)22:20
* xfxf ducks22:20
CarlFKI don't understand something.    it generates a pattern that goes into a frame buffer (is that correct term here?)22:27
tumbleweedyes22:28
CarlFKthat is used to generate?  a signal to send to hdmi out - which works fine22:28
CarlFKit is also encoded to a jpeg - which I am guessing is where the problem is, but I don't see how this is different between atlys and opsis22:29
tumbleweedthe problem we are seeing here is cleary in the encoder or USB stack or the interfaceb etween them22:29
CarlFKI have trouble understanding how the usb stack could cause problem without making the jpeg invalid22:33
CarlFKARG!!! I made the ansible tweeks to the pxe branch22:37
CarlFKon neat. I made a new branch to pu them in.22:40
CarlFK[m]and still mucked it up.  bunch of mv's ended up in the wrong branch.23:01
