Most comments here allude to the FS not being "sync"-ed; however /usr/lib/pm-utils/bin/pm-action (pm-suspend) in pm-utils does sync. I'm reassigning to pm-utils for now, but I rather suspect that this is a driver/hardware issue as we got a relatively low number of such reports.
These logs also point at drivers/hardware issues rather than userspace issues: Mar 3 09:46:43 Kamorka kernel: [40226.138935] Buffer I/O error on device sdb2, logical block 1545 Mar 3 09:46:43 Kamorka kernel: [40226.138941] lost page write due to I/O error on sdb2 ** Changed in: pm-utils (Ubuntu) Sourcepackagename: acpid => pm-utils -- suspend and hibernate may cause data corruption because it doesn't syncs nor umounts external drives previously https://bugs.launchpad.net/bugs/198125 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
