I had used the information from the wiki page DebuggingKernelSuspend "resume-trace" debugging procedure for finding buggy drivers and made the system suspend by sudo sh -c "sleep 720 && sync && echo 1 > /sys/power/pm_trace && pm-suspend" i.e. wait 12 minutes before suspend. So dmesg.log4 may contain trace info from suspend/resume.
My earlier assumption that autofs unmounts the volume seems to be incorrect, point 2. in prerequisites. There are four conditions: 1. a file is opened for writing on a nfs-mounted volume that autofs mounts AND 2. the system is suspended 3. the system is resumed 4. a write operation to the "open" file is performed ==> it is impossible to access the volume on the server -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1544462 Title: automount fails on resume after suspend if file open for writing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1544462/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
