12:24 < fireangel> hi all
12:25 < fireangel> does someone has an uml server at bytemark ?
12:27 -!- AquaJo [~torbofh@pD9E4CA5C.dip.t-dialin.net] has joined #uml
12:27 < AquaJo> rehi
12:28 < fireangel> nobody speaking here... :P
12:32 < AquaJo> well, we could change it *g*
12:34 < fireangel> :)
12:35 < fireangel> AquaJo: are you using uml ?
12:35 < fireangel> I just subscribe an account at bytemark
12:35 < fireangel> I asked them if I could use LVM with UML
12:35 < fireangel> And they told me that it was not recommended
12:35 < fireangel> Because of performance and data recovery
12:36 < fireangel> I'm okay for the data recovery part
12:36 < fireangel> But for the performance problem, I'm still doubting
12:42 < AquaJo> im Using uml, but not with lvm
12:42 < AquaJo> <- is the dadmin for a few douzend UMLs

15:12 < jdike> hi guys
15:13 < frediz> hi there
15:13 < BB> hi
15:25 < wojci> jdike: Hi :)

17:00 < jdike> green: you there?
17:41 -!- Umler [~anon@200.67.146.73] has joined #uml
17:47 < frediz> Ok Ive just made a gentoo root_fs
17:47 < frediz> during the boot I get 2 strange messages : 
17:47 < frediz> 1:
17:47 < frediz> fsck: fsck.xfs: not found
17:47 < frediz> fsck: Error 2 while executing fsck.xfs for /dev/ubd/0
17:48 < frediz> and then 
17:48 < frediz> 2:
17:48 < frediz>  * Caching service dependencies...bash: line 1: ommand not found
17:48 < frediz> bash: line 1: 01m*: command not found
17:48 < frediz> I can log in, but get a seg fault for everything I use
17:48 < frediz> ideas ?
17:49 < jdike> frediz: UML version?
17:50 < frediz> Linux i686 2.6.0-test2-1um
17:50 < jdike> frediz: Can you try with a recent 2.4 UML?
17:50 < frediz> erf, as soon as I compile one, yes
17:51 < frediz> Im gonna try a few things before
17:51 < jdike> frediz: Is the libc particularly modern?
17:51 < frediz> libc-2.3.2
17:52 < frediz> ompiler version: 3.2.3 20030422
17:53 < jdike> frediz: does it have the new thread stuff in it, for example?
17:53 < BB> have you emerged xfsprogs?
17:53 < frediz> jdike: good question... dont have any idea
17:53 < BB> guess that wont help with the seg fault tho
17:54 < frediz> BB: the point is, its a reiserfs formatted file
17:54 < jdike> frediz: possibly UML isn't supporting the newer stuff correctly
17:54 < frediz> possible...
17:54 < jdike> frediz: and no one has noticed because they haven't booted UML with a libc that uses it
17:55 < frediz> but Im more confident in uml than in my root_fs installation abilities
17:55 < frediz> ... Im looking for something I may have missed
17:55 < jdike> frediz: in that case, a 2.4 UML should work because libc will see that it doesn't claim to do the new things
17:55 < frediz> ok
17:56 < frediz> btw, bash is running...
17:56 < frediz> "less" also
17:56 < jdike> frediz: can you strace something that segfaults
17:56 < frediz> hehe, strace isnt installed
17:56 < frediz> a chroot could help :)
17:57 < BB> the default in gentoo in fstab for / is xfs btw
17:57  * frediz slaps forehead
17:58 < frediz> right I change to ubd stuff but not the fs type
17:58  * frediz confused
17:58 < frediz> wait...
17:59 < frediz> Thats a bit better
17:59 < frediz> thx BB
18:00 < frediz> ok Im gonna chrooting and add some missing stuff
18:00 -!- fireangel [~fireangel@cowmeuh.dyndns.org] has quit [Quit: Maou maou ! :)]
18:03 < jdike> frediz: when you get a strace, can you send it to uml-devel?
18:03 < frediz> if the pb is still here, yep, for sure
18:05 < frediz> jdike: did you add the fix for the network in the 2.6-test3 uml patch ?
18:05 < jdike> frediz: no, that will be in the next one
18:05 < frediz> nice :), thx
18:16 < frediz> jdike: what do you need exactly ? a strace output ?
18:16 < slh____> join #!adm
18:16 < jdike> frediz: yeah, a strace log that ends with a segfault
18:16 < frediz> jdike: any special strace options ?
18:17 < jdike> frediz: no, I don't think so
18:17 < frediz> ok
18:18 < frediz> btw /lib/libc.so.6 is the last .so opened ... most of the time

19:24  * jdike fixes the task_struct leak
19:24 < jdike> and discovers a rather astonishing scheduler bug in the process
19:25 < caker> sounds juicy
19:25 < jdike> maybe :-) the scheduler is subtle in places

19:33 < caker> assignment instead of comparison, or a pointer foul up?
19:34 < caker> or another guess: array bounds?
19:40 < jdike> No, it basically returns an uninitialized value, except the assembly in the i386 context switcher just happens to fill in %eax correctly so it happens to return the right thing
19:44 < caker> ahh, one of those "it works, but it isn't supposed to" bugs .. usually found on accident :-)  love those
