First of all this isn't related to s2ram/disk. Second, this happened here again 3 times. Now kernel complains loudly about access to freed inode. After a reboot fsck tells the following: - Some directory entries point to freed inodes, Which means these files are gone, but I never deleted some of them - Some inodes have shared blocks - Some orpahaned inodes found - Free block counts/bitmaps corrupted. That all happens without any s2ram/disk cycle. However, yet an unusual situation did happen today. I had installed an update to mountall ubuntu package, and it hosed all boot process. I had to reboot many times, and once did hold the power button for 4 seconds. I also used often the SYSRQ+U/SYSRQ+B tool. On the contrary, I did several s2disk cycles, and one did fail, but there was no corruption. I must say that until now, I had never seen any ext3/ext4 corruption, even though there were many many crashes, power failures, forced reboots, etc... Best regards, Maxim Levitsky
