As suggested I upgraded to the latest upstream kernel. The issue persists but with slight variation. After about 2 hours of running the copy the gui froze as already described but this time I could crtl-alt-F1 to a terminal which I was not able to do when the freeze happened with the older kernel. However, once in the terminal I could enter my log in name but the password prompt was never presented. I could press Enter to do a line feed but no password prompt. I left the machine for about 2 hours and the gui showed some sign of refresh, the mouse cursor came back and could be moved, but clicking did nothing, alt-tab was not working and everyting was still frozen. So bug still persists.
I ended up copying the files using rsync which worked without a hitch. Is there anything else I can do to try to debug this issue? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1217627 Title: Ubuntu 13.04 freezes when copying large amount of data from one USB drive to another Status in “linux” package in Ubuntu: Incomplete Bug description: When copying about 1.5TB of data from one 3TB USB drive to another the system totally freezes requiring a hard reset (power button or sysrq- alt-b Details: I have a Lenovo T420 laptop. I am trying to copy data from one USB drive to another but after some time has elapsed (up to 2 hours) the entire system becomes unresponsive. I am usually only running a web browser (happens with both Firefox and Chrome). The mouse cursor is still active for a few minutes but nothing else is responsive. The mouse cursor will then also vanish and trying to change to a terminal (ctrl-alt-F1 for example) is not possible. The laptop BIOS is up to date. Things I have done: - File tranfer was using Nautilius so installed Nemo but same issue. - I set up a netconsole and monitored remotely. The plug in of the USB drives was detected but nothing else sent to remote console after the hang. - I can still ping the laptop but cannot ssh into it after the hang - I can see nothing obvious in syslog or dmesg that gives an indication of what is wrong but I don't really understand most of what is in there anyway. - I thought initially that it was Firefox so totally removed and just used Chrome. Issue persisted. - I ran memtest86+ which showed no errors so RAM is not the issue. - I ran installed cpuburn and ran burnP6. CPU maxed out but no hang. So CPU isnot the issue - I then thought it may be an issue with my install do i did a fresh install of Ubuntu 13.04, did all updates and tried again. Same result - I have a HP 6730s laptop so I did a fresh install of 13.04 and tried on it. Same result, hangs after about 20 minuts or so of copying files so the issue is not specific to my Lenovo laptop - I did the transfer on another laptop I have that is running Windows XP and tranfer is fine. So issue is not with USB drives (unless WIndows masks any issues somehow) Output of cat /proc/version_signature Ubuntu 3.8.0-29.42-generic 3.8.13.5 ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: linux-image-3.8.0-29-generic 3.8.0-29.42 ProcVersionSignature: Ubuntu 3.8.0-29.42-generic 3.8.13.5 Uname: Linux 3.8.0-29-generic i686 ApportVersion: 2.9.2-0ubuntu8.3 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: marty 1931 F.... pulseaudio Date: Wed Aug 28 10:03:13 2013 HibernationDevice: RESUME=UUID=a8dd9ab0-fa20-4a6c-9c60-a01ac78ba212 InstallationDate: Installed on 2013-08-26 (1 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Release i386 (20130424) MachineType: LENOVO 4180AF7 MarkForUpload: True ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.8.0-29-generic root=UUID=63915d14-86d4-4029-8f38-f4f84381bba5 ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-3.8.0-29-generic N/A linux-backports-modules-3.8.0-29-generic N/A linux-firmware 1.106 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) WifiSyslog: dmi.bios.date: 10/06/2011 dmi.bios.vendor: LENOVO dmi.bios.version: 83ET65WW (1.35 ) dmi.board.asset.tag: Not Available dmi.board.name: 4180AF7 dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr83ET65WW(1.35):bd10/06/2011:svnLENOVO:pn4180AF7:pvrThinkPadT420:rvnLENOVO:rn4180AF7:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 4180AF7 dmi.product.version: ThinkPad T420 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1217627/+subscriptions -- 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
