[Kernel-packages] [Bug 928895] Re: filesystem deadlock sshfs precise kernel 3.2.0-12-generic
Angelicfury1, thank you for your comment. So your hardware and problem may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into the default Ubuntu kernel (not a mainline one) via: ubuntu-bug linux For more on this, please read the official Ubuntu documentation: Ubuntu Bug Control and Ubuntu Bug Squad: https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue Ubuntu Kernel Team: https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Filing_Kernel_Bug_reports Ubuntu Community: https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette When opening up the new report, please feel free to subscribe me to it. As well, please do not announce in this report you created a new bug report. Thank you for your understanding. Helpful bug reporting tips: https://wiki.ubuntu.com/ReportingBugs -- 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/928895 Title: filesystem deadlock sshfs precise kernel 3.2.0-12-generic Status in “linux” package in Ubuntu: Expired Bug description: On precise i was rsyncing files over a sshfs mountpoint. The transfer itself is extremely slow in overall but that does not indicate a bug itself. But while the transfer was running i started browsing files with the filemanager also over the mountpoint and now it froze the rsync file transfer and the filemanager (Thunar to be specific). Rsync and Thunar are frozen and don't respond to signals. It's a multicore 64 bit system.
