I encountered something very similar yesterday, with 2.6.32-rc3. When doing sync after accidentally removing a mounted USB stick, sync got stuck, so I resorted to SysRq+S/U/B. Unfortunately this was also just after an apt-get upgrade. The result was the same, corrupted ext4 partitions, shared blocks, orphaned inodes, free bitmap errors. Only recently written files seem to be affected, in my case upgraded stuff in / and configuration files in /home. -- Jindrich Makovicka _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
