Yep, fantastic. I can reproduce this problem anytime so I can test it. > If you can help me make a reproducer, that would be great. I can test myself then. Here is some info from a faulty system. Hope it helps: ***** fstab mount: //192.168.1.10/FPGNAS /mnt/FPGNAS_CIFS cifs _netdev,x-systemd.requires=network-online.target,async,nosuid,nodev,noexec,iocharset=utf8,file_mode=0640,dir_mode=0750,uid=1026,gid=100,credentials=/etc/.cifspwd,rw 0 0 ***** mount info: //192.168.1.10/FPGNAS on /mnt/FPGNAS_CIFS type cifs (rw,nosuid,nodev,noexec,relatime,vers=3.1.1,cache=strict,username=fprietog,uid=1026,noforceuid,gid=100,noforcegid,addr=192.168.1.10,file_mode=0640,dir_mode=0750,iocharset=utf8,soft,nounix,serverino,mapposix,rsize=4194304,wsize=4194304,bsize=1048576,echo_interval=60,actimeo=1,closetimeo=1,_netdev,x-systemd.requires=network-online.target) ***** cp from a file to a file both in same share: # cd /mnt/FPGNAS_CIFS/tmp /mnt/FPGNAS_CIFS/tmp# touch sample1.txt /mnt/FPGNAS_CIFS/tmp# cp sample1.txt sample2.txt Terminado (killed) After that error the CIFS mount become unusable as any operation just hangs. ***** The remote cifs server is a Synology DS213j NAS. Samba version is: # smbd -V Version 4.15.9 Synology Build 42934, Jul 5 2023 16:52:06 Please, let me know if I can give you any other info that helps to solve the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060919 Title: Remote filesystems mounted as CIFS not working after update to Kernel "6.5.0-27-generic #28-Ubuntu" (amd64) or Kernel "6.5.0-1014-raspi #17-Ubuntu" (aarch64).
