You will find attached the output of lspci -vv and lspci -vvn. When doing: sync; echo 1 > /sys/power/pm_trace; /etc/acpi/sleep.sh force as outlined in https://wiki.ubuntu.com/DebuggingKernelSuspend, the relevent lines are [ 1.106193] Magic number: 0:798:695 [ 1.106289] hash matches drivers/base/power/resume.c:46 [ 1.106436] hash matches device 0000:00:00.0
Note that this was done with 2.6.20-29 (latest security update updated it), and now it will actually reach suspend state, but still wouldn't wake-up (blank screen). Just to cover all bases, I restored POST_VIDEO=true (the distribution default) in /etc/default/acpi-support. And now it successfully wakes-up, which it didn't before (with any kernel I tried). So apparently, someting fixed it between 2.6.20-28 and -29, so for the first time (for me) sleep would seems to work out of the box on the Macbook Pro. Most likely this bug can be closed, but I still included all relevent info in case it is usefull to developpers or anyone else. ** Attachment added: "lspci_vv.txt" http://launchpadlibrarian.net/8037178/lspci_vv.txt -- 2.6.20-15.27 => 2.6.20-16.28 Suspend to RAM regression on MacBook Pro https://bugs.launchpad.net/bugs/118822 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
