Further info: This came up during a 12.10 certification run. The test runs a script in checkbox called meminfo_resource before and after suspend and then compares the output to see if there were any changes. In this case, there was a change.
To give you an example (this is NOT from the failing machine), meminfo_resource outputs just a couple lines taken from the contents of /proc/meminfo: bladernr@klaatu:~/development/checkbox$ ./scripts/meminfo_resource total: 6248673280 swap: 1999630336 As mentioned above, it does this twice, once before suspend and once after suspend. The after suspend command looks like this: meminfo_resource | diff $CHECKBOX_DATA/meminfo_before_suspend - So this seems to indicate that meminfo before suspend had 4054175744k of RAM, and after a suspend had 4054171648, so it lost some memory. The machine in question is an Asus desktop that was enabled for 11.10 and has subsequently failed certification for 12.04 and 12.10. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1071651 Title: memory_after_suspend failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1071651/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
