[Kernel-packages] [Bug 1811723] Re: Samba client freeze during write when using higher than vers=1.0
apport information ** Tags added: apport-collected wayland-session ** Description changed: Hello, My issue is that whenever I try to write new files (copy or move) to my file server something in the samba client freezes and I can't do anything samba until the system is rebooted. To get write access I mount with uid ie "sudo mount //server/share /mountpoint -o user=write,uid=1000". Using this command the server and client negotiates smb protocol version 3.02. When this happens the server is still happily serving files to other machines. If I just read files everything works fine. If I connect from a windows client there is no issue. If I add "vers=1.0" everything works but transfers are really slow. Specifying version 3 produces a fail. Trying the same operation (different hw) with Mint 18 Mate produces the same fault. Trying the same operation (with "vers=3.0" set) using SuSE Leap 15.0 KDE live everything works as expected. Both client and server are running fully updated, as of posting, bionic.
