https://bugzilla.kernel.org/show_bug.cgi?id=16019 Summary: Resume from hibernate corrupts ext4 Product: Power Management Version: 2.5 Kernel Version: 2.6.33.4-95 Platform: All OS/Version: Linux Tree: Fedora Status: NEW Severity: high Priority: P1 Component: Hibernation/Suspend AssignedTo: power-management_other@xxxxxxxxxxxxxxxxxxxx ReportedBy: lowe@xxxxxxxxx CC: fs_ext4@xxxxxxxxxxxxxxxxxxxx Regression: No Overview: System appears to hibernate successfully. Upon resume at first sight all seems well until one discovers it is no longer possible to write to disk. Steps to reproduce: 1) Hibernate system to disk. (Note suspend to ram seems to work ok). 2) Resume from disk. 3) System starts up ok, but disk seems to be mounted read only. Sometimes resume just fails and system auto reboots itself and fixes the ext4 disk errors. 4) Rebooting seems to fix the disk issues. Expected result: Resume from hibernate should work ok.
