apwhggdh, yes it should, there is cirtianly postinst for it in later versions09:27
apwhggdh, it was a known issue with the initial versions that it did not09:27
apwppisati, next time we do a ti-omap4 rebase we should include the changelog fragment from->to from the original tree.  there is a helper in the tree for this called insert-ubuntu-changes, which adds changlog information to your changelog if you have a startnewrelease already09:43
apwppisati, ./debian/scripts/misc/insert-ubuntu-changes debian.ti-omap4 Ubuntu-3.2.0-3.8 Ubuntu-3.2.0-3.909:44
apwppisati, in theory that puts the right stuff in, its broken it seems, will fix09:44
apwppisati, ahh me being dense.  So it takes a changelog of course ...09:49
apw./debian/scripts/misc/insert-ubuntu-changes debian.ti-omap4/changelog Ubuntu-3.2.0-3.7 Ubuntu-3.2.0-3.809:49
apw+  [ Ubuntu: 3.2.0-3.8 ]09:49
apw+09:49
apw+  * armhf -- add d-i configuration09:49
apw+  * armhf -- disable ABI checks for armhf09:49
apw+  * armhf -- add arch to getabis config09:49
apwppisati, so it does something like that, which you then can commit as 'UBUNTU: rebase to Ubuntu-3.2.0-3.8' or whatever09:50
apwthat way the derivative branch contains hints as to the real changes coming over09:50
apwand also any bug numbers that were fixed in the master branch too09:50
apwppisati, make sense ?09:51
ppisatiuhm, nice, didn't know about it09:55
apwppisati, yeah my fault should have mentioned it before, we use it on like -ec209:56
apwppisati, and it copes with more than one version, so if you rebase forward 4 versions just put the old and new base versions and it will insert multiple sections09:58
apwsmb, any idea if the use of ubuntu-insert-revisions is documented anywhere?09:58
ppisatifriday off, he is not here i think09:59
apwahh good point09:59

ogra_why wouldnt it :)12:44
ogra_we are professionals, you know *g*12:44
vanhoofi have serious paranoia problems with this board :)12:44
ogra_now try armhf :)12:44
vanhoofit's been through a lot :)12:44
vanhoofogra_: it was broken for 6 months :)12:46
ogra_huh ? what was the bug ?12:46
vanhoofogra_: haha12:46
vanhoofogra_: tornado12:46

ogra_oh indeed :)12:46
vanhoofhdmi is hosed on it (no signal)12:47
vanhoofbut serial works12:47
vanhoofand jk- recommended putting it in the dish washer12:47
ogra_ah, then you are one of our server image users :)12:47
vanhoofand what'dya know12:47
vanhoofit works again :)12:47

apwvanhoof, the hdmi works now?  or the board boots now13:02
vanhoofapw: board boots13:02
vanhoofstill no hdmi13:02

alkisgHi, does this screenshot look like it can be caused by a corrupted ext4 filesystem? http://alkisg.mysch.gr/steki/index.php?action=dlattach;topic=4145.0;attach=2676;image13:19
alkisgIt does that when the teacher runs "mksquashfs"13:19
vanhoofogra_: n00b in this space 13:20
vanhoofogra_: but a quick q13:20
vanhoofogra_: would like to add a bit more disk space, any recommendations on what's the best fit, short of a usb device?13:21
vanhoof(if you have a sec)13:21
ogra_well, a bigger SD then ... 13:22
ogra_you only have these two options13:22
vanhoofogra_: best route then?13:22
* vanhoof has a 4gb sdhc card presently13:22
ogra_Sd is indeed slower than USB13:22
ogra_i would keep the 4G and have a build chroot on a USB disk (for speed)13:23
ogra_beyond that 4G should suffice for smaller stuff indeed, especially if you use the server image13:23
vanhoofyeah server image, but have abused a bit of the free space with some local builds :)13:24
ogra_(you can delete the package pool on the server image (see sources.list.d) that will give you a lot extra space)13:24
ogra_we shipe quite a big archive inside the image (so you can install server packages without needing network)13:25
ogra_*ship13:25
vanhoofoh yeah13:27

WipsterI have found that if I disable dma with the boot option libata.dma=0 I cant access my harddrive and get READ MULTIPLE errors in dmesg, this relates to bug #89777716:32

mfischis there a way to tell if a what parts of kernel firmware are being used at runtime?  something like lsmod for kernel-firmware...?17:37
tgardnermfisch, there is generally something in dmesg, though it may be driver specific. You can also look in the udev logs17:41
mfischtgardner: yeah I knew about the logs.  sounds like that's the only option17:41
tgardnermfisch, what device ?17:42

argestgardner, are there flags I can pass to the kernel to provide more verbose wifi/iwlagn messages? 19:08
tgardnerarges, dunno, I haven't been at that level in awhile.19:09
tgardnerhave you created the bug report yet ?19:09

wamtyhas 'CONFIG_SECURITY_CAPABILITIES' been removed from recent (3.0.x) kernels?19:12
infinitywamty: Someone else already answered.19:17
keeswamty: yup19:17
wamtybut why removed?19:18
wamtycaps are the default module i think19:18
keeswamty: correct. it's no longer optional. :)19:18
keesi.e. no config, because it's always there.19:18
argestgardner, wow so not only does it disconnect me in n-mode wifi in 3.0.0-12 , but the router goes into a bad state that requires a reset (even wired connection to it doesn't work). For some reason 3.0.0-14, 3.2 seem to work for me in n-mode. now i want to make sure this isn't a router issue, I'm going to check for firmware upgrades.19:23
wamtyi can log -p security/Kconfig to get the IDs of interesting pieces19:25
wamtyi guess19:25
tgardnerarges, thats a good trick borking your AP19:45
