Devin_Hey whats up14:59
skaetrtg, what changed with that lastest kernel update (-22)?   I just applied it,  and am black screen on boot up.15:03
rtgskaet, kamal's i915 patches are wrecking the world. we're working on it.15:04
rtgskaet, you're kind of late to the party. How often do you update ?15:05
skaetrtg, , daily.  But seem to have had some glitch on the updates.15:06
rtgskaet, have you booted with -21 to make sure its not an intermittent issue ?15:07
* skaet experimenting15:09
* kamal seriously considers just calling in sick today :-( what a mess15:25
kamalskaet: questions if you could determine whether the problem is in .21 also, that would be *very* helpful (one set of i915 patches went into .21, then another went into .22 -- I'm hoping the problem is isolated to .22)15:26
kamals/questions/questions:  #1/15:26
kamalskaet: question #2:  the black screen problem ... does it *stay* black, or does it light up again when it reaches the X login screen?15:27
DevinHey can I get a hand compiling a kernel15:28
skaetkamal,  it stays black.        Trying get 15.21 on the system now. 15:30
kamalskaet: ok, thanks very much15:31
tjaaltonsmb: thanks for testing, now you could also check a newer mainline kernel to see if it's fixed there :)15:33
smbtjaalton, Yeah, yeah. Maybe when I get bored... iow not today. :-P15:35

=== joshhunt_ is now known as _joshhunt_
jjohansenogasawara: hey so I am not going to request IMA for quantal, it forces tpm on, and there have been issues in the past that cause slow boot and suspend/resume failures. They are most likely dealt with but there isn't enough information, and its too late to be testing with this release15:50
jjohanseninstead I am just going to set up a ppa and point people to that15:50
rtgjjohansen, there appears to be some effort going into IMA for 3.6 (and I assume 3.7).15:51
jjohansenrtg: yep, there is the ima appraisal stuff, and a few other patches15:51
rtgjjohansen, IMA is on my list of things to get smart about for ubuntu-r15:52
jjohansenrtg: ah mine too15:56
rtgjjohansen, I'm convinced that its gonna be required in certain scenarios. The fed already has an attestation specification that I was reading about last week.15:57
jjohansenrtg: yeah I think so too15:59
ogasawarajjohansen: ack, thanks15:59
* ppisati -> gym16:08
ckingjust hope IMA doesn't suck loads of memory like it used to16:11
rtgcking, lets hope it doesn't just plain suck like it used to :)16:12
* herton -> lunch16:13
ckingheh16:13
jjohansencking: that has been fixed, enabling it does have some overhead, it expands the inode some, but the radix tree has been replaced with an rbtree, and there have been several locking improvements as well16:13
ckingjjohansen, ah good, the radix tree was a memory hogger16:14
jjohansencking: yep, and so was having to track each inode externally. Expanding the inode reduced the total overall cost at the expense of chewing up 16 or so bytes/inode even if ima is not in use16:15
ckingjjohansen, ok, so some minor impact on small memory systems then16:16
jjohansencking: yes unfortunately16:17
jjohansencking: this isn't exactly what is there now but it is a pretty good guide to how the fixes changed it https://lkml.org/lkml/2010/10/18/64416:18
