Have run cking's s3 test script as per https://wiki.ubuntu.com/Kernel/Reference/S3SystemTapDebug.
locatehang, run immediately after reboot (because the machine hung at a lit black screen as before), printed: $ ./locatehang Looking for function that matches hash from the Magic Number from the kernel log. Magic: 12:64:42 maps to hash: a3d2c Hash matches: acpi_hw_write_pm1_control() (address: 0) The kernel probably wrote to the southbridge the magic to put the machine into suspend or hibernate and then the machine hung. Generally this means that the machine did not wake up and get back to the kernel resume successfully which normally indicates a BIOS issue. All s3-*.log files were 0 bytes in size: $ ls -l s3*.log -rw-r--r-- 1 root root 0 Dec 16 16:45 s3-devices.log -rw-r--r-- 1 root root 0 Dec 16 16:45 s3-error.log -rw-r--r-- 1 root root 0 Dec 16 16:45 s3-systemtap.log -rw-r--r-- 1 root root 0 Dec 16 16:45 s3-tasks.log -rw-r--r-- 1 root root 0 Dec 16 16:45 s3-test.log -rw-r--r-- 1 root root 0 Dec 16 16:45 s3-trace.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/904261 Title: Lenovo U300s does not suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/904261/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
