twblilstevie: have you seen this? http://paste.ubuntu.com/770683/00:58
twb"fakeroot, while creating message channels: Function not implemented This may be due to a lack of SYSV IPC support."00:58
lilsteviethat I have not00:59
lilstevietwb: also, LP0 fixed00:59
twbcoo00:59
twb...l00:59
twblilstevie: does "fakeroot pwd" work for you?01:00
infinityI would hope so...01:01
twbWTF have I done01:01
* lilstevie doesn't even have fakeroot installed01:01
twblilstevie: it's mainly used when building packages01:02
lilstevieyeah I know01:02
lilstevieI have it on the trim01:02
lilsteviewhere I build my packages01:02
infinityWho's sending me a trim for Christmas?01:02
infinityAnyone? :)01:02
* infinity hears crickets.01:02
lilstevielol01:02
twblilstevie: it works if I update-alternatives and change it to use fakeroot-tcp instead01:04
lilstevielol01:05
twbWhich is Bad Juju because IIRC that breaks something else01:05
lilstevieI currentlly have no wifi on my tf101 so I cant install fakeroot to tell you my result01:05
twbk01:05
twblilstevie: FYI, guy next to me can reproduce fakeroot-sysv issue on his tf10101:57
lilstevieok01:59
infinitytwb: Kernel built without sysvipc?02:01
infinityCONFIG_SYSVIPC=y02:01
infinityCONFIG_SYSVIPC_SYSCTL=y02:01
infinityCONFIG_SYSVIPC_COMPAT=y02:02
infinityProbably want all of those for fakeroot to not be a sad panda.02:02
twbinfinity: I didn't build the kernel02:03
* twb points at lilstevie!02:03
twbscary monkey style02:03
twbThere's no /boot/config either :-(02:04
doko\o/ it's done: https://launchpad.net/builders:  armhf11empty02:04
twbAha, /proc/config.gz tho02:04
twbYep, sysvipc is off.  FAIL.02:04
lilstevienot set02:04
lilsteviewill fix later02:04
twbNo rush, fakeroot-tcp works for now02:04
lilstevieI really don't give an f right now :)02:05
infinitydoko: \o/02:05
twbI will have to ring up your girlfriend and tell her bad things about you so she leaves you and you have more time for work02:05
infinitydoko: I'll see if there are any obvious things I can unsnag tomorrow.  And keep an eye on stuff here and there while I'm on VAC.02:05
lilstevietwb: lol. I don't give an f because I am working on something else on the project right now so that would acomplish nothing02:06
twbOkey dokey02:07
* twb puts down the phone02:07

twb16:20 <twb> mikef: battery stats per hour, gave it power just after penultimate entry http://paste.debian.net/149276/05:23
twbSo the TF101 (running Ubuntu) has a discharge rate of 12% to 14% per hour (of the onboard battery).  That works out to be about 7.14 hours of life.  The dock is half as much battery again, so that comes to about 10.7 hours of life with my current config.05:24
twb*without* sleeping or screen blanking on inactivity05:24
twbbrightness is at 157/255 (default at boot time)05:25
twblilstevie: ^^05:33
twbAnybody riced up stuff to save power on the TF yet?  powertop doesn't look to be very helpfu05:33
lilstevietwb: my average consumption is 10% per hour05:36
twbThe only thing it recommends that I can see is /proc/sys/vm/dirty_writeback_centisecs05:36
twbWhich is 6000 and it thinks 1500 is better, but it isn't05:36
twblilstevie: hum05:36
twblilstevie: well, I am using an offboard keyboard, and wifi05:37
twbhttp://www.lesswatts.org/tips/disks.php et al05:38
lilstevieI get 19hours 40 with no power management05:38
lilsteviewifi on05:38
lilsteviebut using the dock keyboard05:38
twbBe interesting to know what else is different05:38
lilsteviewith LP0 suspend to ram though :p05:39
twbThere is autosuspend for the keyboard power, but if you turn it on, the keyboard won't wake from sleep :-(05:39
lilstevieyou probably don't want to know05:39
lilsteviealso my wake is based off the dock "lid open switch"05:40
twbSurely the 19.6 hrs doesn't count the hours that it's suspended to ram05:40
twbIn which case suspend to ramdoesn't matter05:40
lilstevie19.6hours was without LP005:41
twbThe dock battery is half the size of the tablet battery, right?05:42
lilstevieno05:42
lilsteviesame size05:42
lilstevieidentical05:42
twbOh, OK05:42
twbIn that case I should get ~14 hours atm05:42
lilstevielast 4.4h used 1% battery05:43
lilstevie:)05:43
lilstevieonly issue with LP0 I can see at the moment is the battery does not charge from the dock while in that mode05:45
twbso you think it's like a car, where the "empty" mark is WAY above the actual empty level?05:45
lilsteviethe dock does not drain past 3%05:46
twbWell yeah, not counting that05:46
lilstevieand not "way above"05:46
lilsteviebut still a little bit above05:46
lilsteviejust not all batterys are created equal05:47
lilsteviebatteries even05:48
twbIs irqbalance useful on tf?05:56
twbAlso for some reason my load average never drops below 105:57
cmcmanisGreetings ubuntu-arm, is it a known bug that the current build has EXT4 journal corruption bugs?06:01
twbcmcmanis: current build on what platform?06:01
cmcmanissorry pandaboard06:01
cmcmanisGot a new Pandaboard-ES and put the current Ubuntu on it06:01
cmcmanisIt corrupts the EXt4 journal and then I have to reboot. I can reproduce by just dding from /dev/zero to a file06:02
infinitycmcmanis: Define "current Ubuntu".06:04
infinitycmcmanis: But I have no such issues on my Panda.  Is this running on an SD card?06:05
infinitycmcmanis: (If so, I'd suspect your SD is dying)06:05
cmcmanissorry, the build that is referenced off the pandaboard.org site one sec06:05
cmcmanisubuntu-11.10-preinstalled-server-armel+omap4.img.gz06:06
cmcmanisSD is brand new, kingston class 1006:06
infinityNew doesn't mean much. :/06:06
infinityI can tell you for sure that a fresh install of oneiric shows no such weirdness on any Pandas here.06:07
cmcmanisfair enough06:07
infinityI actually only have on card I've never managed to kill.  And I suspect that's more luck than anything else.06:08
infinitySD and random access don't really get along.06:08
cmcmanistrue that06:08
infinity(If you have a USB HDD for your Panda, I'd recomend grabbing a netboot image, stuffing that on an SD, and installing to a hard drive)06:08
cmcmanisHmmm that is an interesting idea.06:09
twb17:02 <cmcmanis> It corrupts the EXt4 journal and then I have to reboot. I can reproduce by just dding from /dev/zero to a file06:16
twbThat sounds to me more like the filesystem is bigger than the disk or something06:16
twbOr the blocks where teh journal lives aer toast06:16
lilstevietwb: it would be the latter rather than the former06:17
lilsteviecause unless the SD card is <2GB that wouldn't happen06:17
cmcmanisaye, that would cause it but I've checked the partition multiple times, and can read and write both the first and last blocks (tested using dd)06:17
twbI just prefer to blame users, not hw :P06:18
cmcmanisIts and 8g card btw06:18
cmcmanisIt came in a twin pack and I'm putting Android ICS on the other one we'll see if it has a similar issue06:18
* ogra_ scratches head about the eglibc build09:22
ogra_i wonder why the same package is built on two different builders09:25
ppisatiogra_: becasue you keep hammering those poor builders and they are revolting againt you now! :)09:36
ogra_haha09:37
ppisatiogra_: stop harassing the builders!09:37
ogra_the hammering seems to have stopped last night09:37
ogra_queue is largely empty09:37
ppisatiogra_: btw, did you sort out the ac100 "non booting kernel" problem? i read it could be toolchain related09:43
ogra_ppisati, well, in the package we have there are some issues with devices having hynix RAM, the micron ones seem to work fine ... with the new checkout that was rolled with gcc 4.6.2 it seems everything is broken10:18
ppisatiogra_: crap10:26
ogra_yeah10:26
