[Bug 65856] Re: Excessive battery usage in ACPI sleep
The 18 month support period for Edgy Eft 6.10 has reached it's end of life. As a result, we are closing the linux-source-2.6.17 Edgy Eft kernel task. ** Changed in: linux-source-2.6.17 (Ubuntu) Status: New = Won't Fix -- Excessive battery usage in ACPI sleep https://bugs.launchpad.net/bugs/65856 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I am marking this bug as Fix Released against the Feisty kernel based off comment 3. ** Also affects: linux-source-2.6.20 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-source-2.6.20 (Ubuntu) Status: New = Fix Released -- Excessive battery usage in ACPI sleep https://bugs.launchpad.net/bugs/65856 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 65856] Re: Excessive battery usage in ACPI sleep
The bug appears to be fixed in Feisty (kernel 2.6.20-15-generic). A 16-hour ACPI sleep consumes only 20% of battery. dmesg mentions radeonfb: forcefully enabling D2 sleep mode on boot and then radeonfb (:01:00.0): switching to D2 state... on suspend. -- Excessive battery usage in ACPI sleep https://bugs.launchpad.net/bugs/65856 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
[Bug 65856] Re: Excessive battery usage in ACPI sleep
Before the upgrade my /var/log/kern.log used to contain these messages: radeonfb (:01:00.0): suspending to state: 2... radeonfb (:01:00.0): switching to D2 state... now I only get radeonfb (:01:00.0): suspending to state: 2... I suppose I should try to modprobe radeonfb force_sleep=1 next.

[Bug 65856] Re: Excessive battery usage in ACPI sleep
I edited /etc/modules and changed the radeonfb line to read radeonfb force_sleep=1 I rebooted, suspended, resumed and checked dmesg -- nothing about going to D2 sleep. I then rebooted and added video=radeonfb:force_sleep=1 to the kernel command line, suspended, resumed and checked dmesg. Nothing about going to D2 sleep. -- Excessive battery usage in ACPI sleep https://launchpad.net/bugs/65856 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
