It should be one of these commits: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-3.0.y&id=7e36f505caf7882b6cc89ecedcd7f26749ef917a https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-3.0.y&id=2c34b4ae8f8228e1ec083be0333426eca4a31357 https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-3.0.y&id=01b140abad66f022ff6dff7cc1307b07281035fa https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-3.0.y&id=c938c22b48302eeb9a6f3cc83f223f37d98ba6f7 > Have you bisected in order to figure out which one is the culprit?

The problem had started with kernel 3.0.72 and all other stable kernels that included these commits (my distro only ships 3.0.x and 3.8.x tree at that time). All other commits from 3.0.71 to 3.0.72 look unrelated to my server setup. Local clients can run up to date kernels without any problems. Other people have reported also issues with ACL on servers since that update. I can reproduce the issue instantly when marking lots of mails as read/unread that leads instantly to corrupt files on the server drive. Because it hosts serious data I can't play too much with that machine. It would be nice if you could point me the the related commit. It will cost me lots of time to build a kernel with the patches reverted one by one and I'm afraid of loosing more data. -Andy -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
