Please remove the "Invalid" status from this ticket. I can confirm that this is a linux kernel issue. This happened to me:
1) Attached a external USB harddrive (an 'oldie': the Lacie 250GB) to PC running Ubuntu 14.04.1 with latest kernel update installed. 2) Formatted the harddrive to ext4, already seeing "end_request: critical target error, dev sdX, sector 0" kernel messages. 3) Installed Ubuntu 14.04.1 to the USB harddrive (by booting the Ubuntu 14.04.1 live installer from a USB stick). 4) Booted from the USB harddrive - no problems at all. 5) Updated ONLY the linux-* packages of the Ubuntu running on the USB harddrive. 6) Rebooted the USB harddrive (which auto-selects the latest kernel version in grub), and the filesystem got completely corruppted. Please note that a VFAT filesystem doesn't get corrupted, but the "end_request: critical target error, dev sdX, sector 0" messages also appear in the syslog. Also tested the following: 1) Ubuntu 14.10 - same issue. 2) openSUSE 13.2 Factory (latest live version) - same issue. Searching the internet showed that other distributions have the same issue, e.g.: - Raspberry Pi: https://github.com/raspberrypi/linux/issues/703 - Ubuntu 14.04: http://unix.stackexchange.com/questions/156704/cannot-mount-fresh-partition-twice - Ubuntu 14.04: with kernel version .35: Bug #1368299 - Xubuntu 14.04: http://ubuntuforums.org/showthread.php?t=2243515 - I also came accros Arch-Linux and Debian-Linux pages describing the same error, but can't find them atm, sorry for that. If you need more details, please let me know, I will be happy to provide them. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1366538 Title: Synchronisation/close /dev/sdi: i/o error on target host To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/parted/+bug/1366538/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
