I haven't tested much, but this corruption was obvious very quickly. I just copied a few megabytes of files and got several corruptions. Most files were compressed, and the easiest file to look at was a text file, and the binary zeros were quickly visible in the text editor. I think you will not have any trouble reproducing this issue.
I didn't need to do checksums, just copy with "cp" and immediately compare with "cmp" or "meld". There was no need to reconnect, purge any caches or anything fancy. -- 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/2049634 Title: SMB 1 broken in kernel 6.5.0.14.14~22.04.7 Status in linux package in Ubuntu: New Status in linux source package in Mantic: New Bug description: Hi all: I upgraded my Ubuntu yesterday and automatically got the newer Linux Kernel version 6.5.0-14-generic #14~22.04.1-Ubuntu. Previously, I was running kernel version 6.2 . I still have a legacy system on the network using SMB protocol version 1.0. With the new kernel version, copying files does not work reliably anymore. Some random byte blocks in the destination files are overwritten with binary zeros. It happens quite often. This is not the first time the Linux guys temporarily break SMB protocol version 1.0, see for example this bug report of mine: https://bugs.launchpad.net/ubuntu/+bug/2033732 I checked package linux-image-generic-hwe-22.04 with Synaptic, and now it lists just 2 versions: 6.5.0.14.14~22.04.7 (jammy-updates) 5.15.0.25.27 (jammy) Is there a way to go back to the latest 6.2 kernel version? How do I prevent Ubuntu from upgrading to 6.5 next time around? I have searched the Internet, but I haven't found yet a usable answer. I don't want to go back all the way to Kernel 5.15 if I can avoid it.
