Additional information. I tried to debug the problem by using /sys/power/pm_trace. I ran it three times and got these results:
1: tty tty3: hash matches 2: [ 1.782132] Magic number: 11:492:139 [ 1.782149] block ram4: hash matches [ 1.782189] acpi device:10: hash matches and 3: [ 1.752158] Magic number: 11:148:291 [ 1.752190] tty tty24: hash matches Just to see if the gfx driver is the problem I replaced the radeon driver with fglrx, but it made no difference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/773969 Title: natty: resume broken (HP Pavilion dv6) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
