Hi, I did the test again today with the following method:
sync echo 1 > /sys/power/pm_trace echo disk > /sys/power/state result: the system will be suspend after this, then push the power button, the system will be reboot, and the boot failed for the first time with the following prompt: booting from local disk... isolinux: Disk error 02, AX = 0201, drive 80 Boot failed: press a key to retry then press a key, the system will be start up. I did two times, the same result, please find the dmesg info in the attachment thanks Kevin ** Attachment added: "C:\My work\log\0621\dmesg.1.log" http://launchpadlibrarian.net/8149579/C%3A%5CMy%20work%5Clog%5C0621%5Cdmesg.1.log -- System halt during resume from S4 on Santa Rosa with Crestline https://bugs.launchpad.net/bugs/119977 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
