Hi, I have a portable Fedora installation configured on my SSD, I have 3 kernels installed: $ rpm -qa |grep kernel\-[3\.] kernel-3.18.0-0.rc4.git1.2.fc22.1.x86_64 kernel-3.18.0-0.rc5.git0.2.fc22.x86_64 kernel-3.17.0-0.rc5.git0.1.fc22.x86_64 I now can only use the 3.17 kernel to boot the system, because if I use the other two kernels, the / will be read-only and X can't start as "Failed to move /var/log/Xorg.1.log to XXX", it's really coincident that I thought it was a X issue and then I found the system is not usable with specific kernels. This makes me wonder about the systemd behavior. Maybe it's caused by a uncompleted unmount from the early stage of boot process? But it's only a gut feeling. Any hints for it? Thanks. PS: 1. fstab: UUID=X / ext4 defaults,noatime,journal_async_commit 1 1 UUID=Y /boot ext4 defaults,journal_async_commit 1 2 UUID=Z /home ext4 defaults,noatime,journal_async_commit 1 2 2. systemd-217-4.fc22 Yours sincerely, Christopher Meng http://cicku.me -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
