script to get acpi tables
Dmesg after suspend with pm_test
Description unggnu 2010-03-18 02:02:55 UTC
I am using current Ubuntu 10.10 testing branch. If I suspend the system everything seems to work fine but as soon as I power it on again the system boots like after a normal shutdown. The same happens with the mainline Kernel 2.6.33 but it works fine with Windows XP.

Created attachment 25576 [details] script to get acpi tables please use this script as root user to get all the acpi tables of your laptop.
Comment 2 Zhang Rui 2010-03-18 06:49:20 UTC
please build a kernel with CONFIG_PM_DEBUG=y, CONFIG_ACPI_DEBUG=y and run the following test, 1. echo core > /sys/power/pm_test 2. echo mem > /sys/power/state does the system resume back after about 10 seconds?
Comment 4 unggnu 2010-03-18 09:48:39 UTC
I have used the mainline kernel 2.6.33 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33/ and it resumed after about 10 seconds with the described method. But it seems to be only standby or something like that since the fan never stopped rotating.

Btw. just for the records with the Ubuntu Kernel 2.6.32 I got this message on startup in dmesg: [ 18.066808] ACPI: I/O resource vt596_smbus [0x400-0x407] conflicts with ACPI region SMOV [0x400-0x406]
Comment 7 Rafael J. Wysocki 2010-03-19 19:21:22 UTC
What do you normally do to suspend it?
Comment 8 unggnu 2010-03-19 19:29:36 UTC
Thanks for your reply. I use the Gnome Suspend function but the same happens if I run "sudo pm-suspend" in console.
Comment 9 Rafael J. Wysocki 2010-03-19 19:31:04 UTC
What kind of graphics hardware/driver is used?
Comment 10 unggnu 2010-03-19 19:43:35 UTC
01:00.0 VGA compatible controller : ATI Technologies Inc R360 NJ [Radeon 9800 XT] [1002:4e4a] The open radeon driver with KMS is used.
Comment 11 unggnu 2010-03-19 19:50:17 UTC
Ok, it seems that according to another bug report about this pc suspend works fine with 2.6.31 and 2.6.28 Kernel of Ubuntu Karmic and Jaunty except of some graphic glitches. So it seems to be a regression. I have to recheck it with a Karmic Live CD though.
Comment 12 Rafael J. Wysocki 2010-03-19 19:57:40 UTC
Would it be possible to try without KMS and/or from runlevel 3 (ie. no X)?
Comment 13 unggnu 2010-03-19 22:39:29 UTC
Ok, I have the same problem with the Karmic Live CD. Windows XP still works fine so it shouldn't be a hardware error. The same happens with radeon.modeset=0 and without X (I suppose recovery mode with KMS should be similar).
Comment 14 Rafael J. Wysocki 2010-03-19 22:44:57 UTC
In that case there seems to be a platform (BIOS/firmware) problem with the box we're not aware how to handle at the moment. We're in the process of adding some ACPI-related fixes to the kernel that in theory might be related to the issue with your system. Anyway, if that is a regression, it would be very helpful if you could identify the change that caused the failure to start appearing (eg. by means of bisection).
Comment 15 unggnu 2010-03-20 11:07:15 UTC
After removing a USB voice communication device suspend seems to work fine at least with Ubuntu Lucid. It also works with the mainline Kernel but there are some graphical problems but this has something to do with radeon or similar since the system shuts down after ctrl + alt + del and or on acpi events. I don't know why Windows XP hasn't this problem but since suspend works without the SideWinder Game Voice I am closing this report. Sorry for taking your time.
