On my laptop I am using the ubuntu in persistent mode with a backing files: casper-rw, home-rw. For some time in the new editions of ubuntu [ 15.04 / 15.10 / 16.04 daily (15.12) ] I meet with error: blk_update_request: I/O error, dev loop ... , sector ... . am sure it is not a hardware problem. Please, could you try reproduce this issue `/proc/cmdline` BOOT_IMAGE=/Ubuntu/16.04/desktop-amd64/casper/vmlinuz.efi append noprompt boot=casper intel_iommu=on toram showmounts persistent- path=/Ubuntu/16.04/desktop-amd64 persistent iso- scan/filename=/Ubuntu/16.04/xenial-desktop-amd64.iso cdrom-detect/try- usb=true `kern.log` Dec 15 21:49:25 ThinkPad kernel: [ 11.507021] Bluetooth: BNEP socket layer initialized Dec 15 21:49:25 ThinkPad kernel: [ 11.513208] blk_update_request: I/O error, dev loop0, sector 1376280 Dec 15 21:49:25 ThinkPad kernel: [ 11.544996] blk_update_request: I/O error, dev loop0, sector 1364008 Dec 15 21:49:26 ThinkPad kernel: [ 11.655626] IPv6: ADDRCONF(NETDEV_UP): wlp3s0: link is not ready Dec 15 21:49:26 ThinkPad kernel: [ 11.656563] IPv6: ADDRCONF(NETDEV_UP): enp0s25: link is not ready Dec 15 21:49:26 ThinkPad kernel: [ 11.884604] IPv6: ADDRCONF(NETDEV_UP): enp0s25: link is not ready Dec 15 21:49:26 ThinkPad kernel: [ 12.080950] usbcore: registered new interface driver cdc_wdm Dec 15 21:49:26 ThinkPad kernel: [ 12.089352] qmi_wwan 2-1.4:1.0: cdc-wdm0: USB WDM device Dec 15 21:49:26 ThinkPad kernel: [ 12.089629] qmi_wwan 2-1.4:1.0 wwan0: register 'qmi_wwan' at usb-0000:00:1d.0-1.4, WWAN/QMI device, 86:f3:f1:57:ac:04 Dec 15 21:49:26 ThinkPad kernel: [ 12.089851] usbcore: registered new interface driver qmi_wwan Dec 15 21:49:27 ThinkPad kernel: [ 13.014113] blk_update_request: I/O error, dev loop2, sector 776360 Dec 15 21:49:27 ThinkPad kernel: [ 13.026856] blk_update_request: I/O error, dev loop2, sector 777792 Dec 15 21:49:27 ThinkPad kernel: [ 13.406901] e1000e: enp0s25 NIC Link is Up 100 Mbps Full Duplex, Flow Control: Rx/Tx Dec 15 21:49:27 ThinkPad kernel: [ 13.406909] e1000e 0000:00:19.0 enp0s25: 10/100 speed: disabling TSO Dec 15 21:49:27 ThinkPad kernel: [ 13.406948] IPv6: ADDRCONF(NETDEV_CHANGE): enp0s25: link becomes ready Dec 15 21:49:27 ThinkPad kernel: [ 13.411598] blk_update_request: I/O error, dev loop0, sector 1364024 Dec 15 21:49:27 ThinkPad kernel: [ 13.525480] blk_update_request: I/O error, dev loop2, sector 778064 Dec 15 21:49:28 ThinkPad kernel: [ 13.733896] Bluetooth: RFCOMM TTY layer initialized Dec 15 21:49:28 ThinkPad kernel: [ 13.733906] Bluetooth: RFCOMM socket layer initialized Dec 15 21:49:28 ThinkPad kernel: [ 13.733912] Bluetooth: RFCOMM ver 1.11 Dec 15 21:49:28 ThinkPad kernel: [ 13.758583] blk_update_request: I/O error, dev loop0, sector 1360048 Dec 15 21:49:28 ThinkPad kernel: [ 13.765377] blk_update_request: I/O error, dev loop0, sector 1364032 Dec 15 21:49:28 ThinkPad kernel: [ 13.778920] blk_update_request: I/O error, dev loop0, sector 1364040 Dec 15 21:49:28 ThinkPad kernel: [ 13.785037] blk_update_request: I/O error, dev loop0, sector 1364048 Dec 15 21:49:28 ThinkPad gnome-session-binary[3083]: Entering running state Dec 15 21:49:37 ThinkPad kernel: [ 22.759620] blk_update_request: 15 callbacks suppressed Dec 15 21:49:37 ThinkPad kernel: [ 22.759623] blk_update_request: I/O error, dev loop0, sector 1364072 Dec 15 21:49:37 ThinkPad kernel: [ 22.803618] hidraw: raw HID events driver (C) Jiri Kosina Dec 15 21:49:37 ThinkPad kernel: [ 22.806751] Bluetooth: HIDP (Human Interface Emulation) ver 1.2 Dec 15 21:49:37 ThinkPad kernel: [ 22.806758] Bluetooth: HIDP socket layer initialized Dec 15 21:49:37 ThinkPad kernel: [ 22.811095] hid-generic 0005:0D62:01BF.0001: unknown main item tag 0x0 Dec 15 21:49:37 ThinkPad kernel: [ 22.811211] input: Bluetooth Mouse as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.4/1-1.4:1.0/bluetooth/hci0/hci0:11/0005:0D62:01BF.0001/input/input17 Dec 15 21:49:37 ThinkPad kernel: [ 22.811384] hid-generic 0005:0D62:01BF.0001: input,hidraw0: BLUETOOTH HID v1.39 Mouse [ Bluetooth Mouse] on ec:55:f9:fa:c6:1d Dec 15 21:50:41 ThinkPad kernel: [ 86.683594] blk_update_request: I/O error, dev loop2, sector 2343552 Dec 15 21:50:41 ThinkPad kernel: [ 86.690626] blk_update_request: I/O error, dev loop2, sector 2339064 Dec 15 21:50:41 ThinkPad kernel: [ 86.703606] blk_update_request: I/O error, dev loop2, sector 2057600 Dec 15 21:50:41 ThinkPad kernel: [ 86.713265] blk_update_request: I/O error, dev loop2, sector 2343592 Dec 15 21:50:41 ThinkPad kernel: [ 86.715556] blk_update_request: I/O error, dev loop2, sector 2057608 Dec 15 21:50:41 ThinkPad kernel: [ 86.861531] blk_update_request: I/O error, dev loop2, sector 2339104 Dec 15 21:50:42 ThinkPad kernel: [ 87.954169] blk_update_request: I/O error, dev loop2, sector 2343632 ** Affects: linux-meta (Ubuntu) Importance: Undecided Status: New -- blk_update_request: I/O error https://bugs.launchpad.net/bugs/1526537 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-meta in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
