Mount SMB to local mnt works, but then CPU errors lock up system

[aggie]

So, I have a laptop that runs on our network (only) Win10. I set up a directory on it to be shared.

On this (a different) laptop (Dell Latitude 5500) , same network I run the command to connect to the remote Win10 laptop (the Win10 shared subdirectory) and it connects no problem.

# mount -t cifs -o username=user_name //server_name/share_name  /mnt/

However, about 20 seconds later, this (my 15.6 Dell laptop) machine is un-responsive and I continually hear beeps and X11 / Plasma notifications pop up that there is a CPU 2 or CPU 3 problem. Unfortunately, I can’t capture those (well, maybe with my phone’s camera) …

I have to hold down the Power button for 10 seconds to force the laptop (running 15.6 that connected to Win10 laptop) to turn off, because I can’t get a response via keyboard.

Any thoughts ?

@aggie Sounds like this 'mount -t cifs' then 'ls /mnt' causes "soft lockup - CPU#0 stuck". Can't kill -9 nor init s, etc

I found I needed more to connect to Windows - change winusername and winpassword to the Windows 10 user and password and username to the OpenSUSE name

Also chmod 777 /mnt first - if it is root only it can hang in the kernel.

sudo mount -t cifs -o vers=2.0,username=winusername,password=winpassword,uid=username,gid=users,file_mode=0755,dir_mode=0755 //server_name/share_name /mnt/

Thanks @malcolmlewis … I wonder why I can’t see that post - only if I click on your link ??

I have forum set to English with 15.6 and all categories, but it doesn’t show up in list.

I also did a search before posting.

Anyway, I’m running a directory copy using the suggestion in your linked reply using Konqueror … using Konqueror works like a charm with no side effect.

Weird.

I might try that (as only a simple test) after I’m done using Konqueror, but that extra CLI wasn’t required in the past for me

The Konq workaround takes 2 seconds and it’s running
