bdmurrayjsalisbury: do you have a good understanding of kernel messages yet?20:56
jsalisburybdmurray, you mean IPC messages?20:57
bdmurrayjsalisbury: in bug 901502 in ubiquitysyslog I see the following20:58
ubot4Launchpad bug 901502 in ubiquity (Ubuntu) "I booted into Lubuntu Installation rather than running installation from the live desktop. After inputting my user info and proceeding, the installer encountered an error. (affects: 1) (heat: 6)" [Undecided,New] https://launchpad.net/bugs/90150220:58
bdmurrayDec  7 20:19:58 ubuntu kernel: [   28.071489] loop1: rw=0, want=6496137616, limit=104857620:58
bdmurrayDec  7 20:19:58 ubuntu kernel: [   28.071497] EXT2-fs (loop1): error: ext2_free_branches: Read failure, inode=98360, block=81201720120:58
bdmurrayDec  7 20:19:58 ubuntu kernel: [   28.071499] attempt to access beyond end of device20:59
bdmurrayI'm not positive what that means but I don't think its good ;-)20:59
jsalisburybdmurray, hmm,  looks like the filesystem tried to read past the end of the device.  Strage, could he have been out of diskspace?  If not, could be filesystem corruption.21:01
bdmurrayjsalisbury: well its a ubiquity (installer) bug so it could be the media right?21:01
bdmurrayjsalisbury: a bad cd / dvd21:01
jsalisburybdmurray, yeah that could be, if it was reading the cd.21:02
jsalisburybdmurray, and it probably is the cd, since rw=0 and cds are readonly21:02
jsalisburybdmurray, loop1 refers to a loop device, which is usually a psedo device.21:04
jsalisburybdmurray, which are used by CD ISO and floppy images21:04
bdmurrayis interesting some earlier bugs have some more context21:06
bdmurrayDec 21 21:41:12 ubuntu kernel: [    9.294627] squashfs: version 4.0 (2009/01/31) Phillip Lougher21:06
bdmurrayDec 21 21:41:12 ubuntu kernel: [   14.375581] EXT2-fs (loop1): warning: mounting unchecked fs, running e2fsck is recommended21:06
bdmurrayDec 21 21:41:12 ubuntu kernel: [   14.386433] aufs test_add:252:exe[642]: uid/gid/perm //filesystem.squashfs 0/0/0755, 0/0/077721:06
bdmurrayjsalisbury: thanks, I'm reasonably confident its bad media now.21:08
jsalisburybdmurray, cool, that might be a good new bug pattern :-)21:08
bdmurrayjsalisbury: yeah, searching my local cache of ubiquity attachments found quite a few of these ;-)21:09
jsalisburybdmurray, I have to admit, I haven't played with bug patterns yet, but its definatily on my todo list21:09
bdmurrayjsalisbury: well since you are looking it'd look like this21:10
bdmurray<pattern url="some wiki page">21:10
bdmurray<re key="Package">^ubiquity </re>21:11
bdmurray<re key="UbiquitySyslog">loop1.*Read failure</re>21:11
bdmurray<re key="UbiquitySyslog">attempt to access beyond end of device</re>21:12
bdmurray</pattern>21:12
jsalisburybdmurray, nice.  And the url could point to the wiki page describing how to do md5 checks.21:13
bdmurrayjsalisbury: yep21:13
jsalisburybdmurray, good stuff.  /me just copied an pasted that example in my notes :-)21:14
