[Bug 2060919] Re: cifs: Copying file to same directory results in page fault
I tested two systems with different samba servers and can no longer reproduce the error. Kernel 6.5.0-35 works for me.

Many thanks for the successful investigation! Running the ppa test kernel I can't reproduce the problem anymore. :-) I use two cifs servers running Debian 11, with a couple of shares. With both standard kernels (6.5.0-27, 6.5.0-28) copying inside a share fails immediately on any server. My fstab mounts look like this: //server/store /mnt/store cifs credentials=/home/xxx/.smbpass,uid=1000,gid=1000,_netdev 0 0 -- 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).

Same problem on Debian 12 with kernel 6.1.0-17-amd64 (OK with kernel 6.1.0-16-amd64). -- 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).

I can mount cifs shares with kernel 6.5.0-27, but when copying files from the share to the same share the process is killed everytime. Same effect using bash "cp" or KDE kio copy via Krusader. Running with kernel 6.5.0-26 anything works perfect.
