Hi Omma, I did the test again today, here is the steps:
1. test the resume by the command: sync echo 1 > /sys/power/pm_trace echo mem > /sys/power/state result: the system is suspended, then I try to push the power button to let it resume, a new login xwindow is prompted, all the privious task are disappeared, check the dmesg, there is no useful information. 2. test resume by the command: sync echo 1 > /sys/power/pm_trace /etc/acpi/sleep.sh force result: the system is suspended and resume normally, please see the log: dmesg.1.log 3. repeat the test (2) result: the system can not resume normally. in dmesg.2.log, there are: [ 67.282834] hash matches drivers/base/power/resume.c:46 [ 67.282896] hash matches device 00:0a from the output of the lspci, I can not find 00:0a 4. repeat the test (2) again. result: the system can not resume normally, but can not find any hint in the dmesg.3.log Thanks Kevin ** Attachment added: "C:\My work\log\0621\dmesg.log.tar" http://launchpadlibrarian.net/8149506/C%3A%5CMy%20work%5Clog%5C0621%5Cdmesg.log.tar -- All the task previous are killed after resumed from S3 on Santa Rosa with Crestline https://bugs.launchpad.net/bugs/119976 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
