trapickigood evening!01:22
trapickiI've a problem with an external USB harddisk, a WD Elements 2GB. The only partition has its last sector beyond the last sector reported by the kernel for the disk.01:24
trapickiAny ideas how I find the missing bits to get disk size and partition size matching?01:25
anon^_^Hi, I'm running into a small issue with Kernel 2.6.32-27.49 and dmcrypt02:02
anon^_^when using Truecrypt 7.0a to create an encrypted partition the length of the device, I'm receiving an error, "device-mapper: reload ioctl failed: invalid argument command failed"02:04
anon^_^I haven't had issues with Truecrypt making use of dm-crypt/cryptsetup in the past even on the same distribution in the past (Ubuntu 10.04)02:07
anon^_^presume I caught channel sleeping02:32
anon^_^a little mor information, I was able to create volumes in truecrypt as late as last week before the recent kernel update pushed into Ubuntu 10.04 LTS02:32
anon^_^so this regression appears to be a result of the kernel update02:33
trapickiSome more: My problem is _exactly_ the same as http://ubuntuforums.org/archive/index.php/t-1603349.html, see comments shayno90 October 28th, 2010, 07:58 PM and srs5694 October 28th, 2010, 11:39 PM02:35
trapickifdisk -l output for the 2TB-drive is identical02:36
anon^_^small update, kern log listed the following error after two attempts to encrypt partitioned device03:21
anon^_^http://pastebin.com/Am9YR9QC03:23
anon^_^problem solved, sorry for disturbing chan08:29
anon^_^prior disk was not removed correctly from OS prior to hotswap and insertion of new HDD. This appears to have caused the issue with cryptsetup08:31

QuintasanCan someone take a look at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/694825 ? It's driving me mad, my installation crashes almost right after booting15:06

afunix_hello20:41
afunix_can anybody help me with kernel crashes?20:42
crimsunafunix_: have you read https://wiki.ubuntu.com/Kernel/Debugging ?20:42
afunix_yes. i have strange symptoms20:43
afunix_mainline kernel (2.6.37) is crashing (kernel panic: bounce buffer is not DMA'ble from swiotlb)20:44
afunix_ubuntu maverick last kernel has random hangs20:44
afunix_crashes have appeared after I've upgraded my laptop memory up to 4Gb (x86_64 arch)20:45
afunix_I've run memtest. I've run BIOS built-in hardware tests. Those tools report no errors20:46
Quintasanafunix_: could I see your dmesg? I was wonder if you could have ran into the same issue as me20:47
afunix_i've googled "kernel panic: bounce buffer is not DMA'ble" and found such errors were 2007-2008 in redhat kernels20:47
afunix_http://dl.dropbox.com/u/6312269/dmesg.txt20:48
Quintasanafunix_: uh, that is from a mainline kernel?20:48
afunix_that is current ubuntu20:49
Quintasanoh I see20:49
afunix_i cannot boot mainline20:49
Quintasanafunix_: you get random hang with maverick ones?20:49
afunix_yes20:49
afunix_2.6.35-24-generic x86_6420:50
Quintasanafunix_: You'd better file a bug report, I was trying to grab attention here for at least two days but without success, bugs at launchpad may get adressed faster20:51
afunix_sometimes there are just hags, sometimes I can see blinking caps+scroll lock. sometimes (when I'm in console) I can see a lot of "oops" messages20:51
afunix_well, I'm not sure if it is a memory problem or some real kernel bug20:51
Quintasandid you try booting without the additional RAM?20:52
afunix_yes. When I'm booting with 2Gb it works fine. But when there is 4Gb it hangs.20:53
afunix_but two different memtesting tools says that everything is fine20:53
afunix_I've got such line in dmesg: "Memory: 4041352k/4456448k available (5711k kernel code, 264216k absent, 150880k reserved, 5379k data, 908k init)"20:54
Quintasanwell, I would open a bug in your case, they will just close it if it's your memory's fault in the end20:54
afunix_BIOS reports 256Mb of RAM as absent. So, maybe there is some errors in the way kernel detects and occupies memory20:54
afunix_hmmm. I'll try, but I think that bug report can stay unresolved forever...20:56
