Public bug reported: What I did: using an external USB HDD 500Gb (Hitachi 3.5") created a single linux partition via cfdisk formatted disk with mkfs.ext3 for testing -> works
cryptsetup: $ losetup /dev/loop1 /dev/sdb1 $ cryptsetup luksFormat /dev/loop1 $ cryptsetup luksOpen /dev/loop1 usb500 device /dev/mapper/usb500 exists, so this far is fine now watch this: $ mkfs.ext2 /dev/mapper/usb500 After writing 600-800 of about 3700 blocks, the system freezes. This is repeatable. Second time I had gdm running and did this on tty1, so I got some system messages that hint at not having enough memory (though I have 2Gb working) and thus it started killing processes like gnome-panel, etc. I did repeatedly format external usb disks that were luks encrypted System Information: IBM Thinkpad T42p @1800Mhz 2Gb Ram Ubuntu 9.04 cryptsetup 1.0.6 mkfs (util-linux-ng 2.14.2) ** Affects: cryptsetup (Ubuntu) Importance: Undecided Status: New -- creating ext2/3 fs on cryptsetup/luks usb hdd partition hangs system https://bugs.launchpad.net/bugs/379508 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
