Another problem is that since the CIFS shared drive is mounted. It causes the Nautilus File Explorer to crash, this slows down all my processes on my computer, rendering my computer unable to work at all. It needs to be restarted about every 3 hours after that. Completely rendering us not being able to work efficiently. I have to spend precious work time copying over the files from my shared drive to my local computers, make sure that the files are copied correctly and connection did not died or failed. This is not practical.
A Kernel downgrade is not a long term solution, as dowwn grading the kernel could possibly cause something else to break (for example, VirtualBox, which relies on the linux kernel to work properly). It also potentially introduce vulnerability to attack. Given that downgrading could cause more problem, it is just not safe to do for me. As much as I like Ubuntu, using it for 10+ years now, this has failed big time. Surely will look into other linux distro or switching over to Mac next time I get a new computer. -- 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/1687273 Title: Shared folder randomly not mounted Status in cifs-utils package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: Hello Everybody, since last update from ubuntu 16.04.2, last night, my servers are randomly not able to read and write from shared folders. I got this message: lsof: WARNING: can't stat() cifs file system /mnt/record Output information may be incomplete. lsof: WARNING: can't stat() cifs file system /mnt/record Output information may be incomplete. lsof: WARNING: can't stat() cifs file system /mnt/record Output information may be incomplete. ... rsync: ERROR: cannot stat destination "/mnt/record/": Host is down (112) rsync error: errors selecting input/output files, dirs (code 3) at main.c(652) [Receiver=3.1.1] This comes from my cron script. When I type df -h it takes sometimes very long to get the list. And it also can be that the mounted share is disconnected and I have to mount -a (what also takes long) again.
