Joseph: thanks for the suggestion. I've downloaded Linux-3.1 (final) from kernel.org (http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.1.tar.bz2) and created Ubuntu packages, using the Ubuntu kernel build instructions here https://wiki.ubuntu.com/KernelTeam/GitKernelBuild
I rebooted and tested writing to the CIFS share with my custom 3.1 kernel, and unfortunately the problem still exists. ** Tags removed: needs-upstream-testing ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/879228 Title: files written to CIFS share are sometimes corrupted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/879228/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
