Description brian curtin 2005-11-09 04:43:43 UTC

I am getting a barrage of ACPI-1041 errors, which lead up to my computer reaching a critical temperature and then shutting itself down. I am running an HP zd7180us laptop, which runs a bit hot anyways, but it never did anything like this in the past. After it shuts down, I check /var/log/messages in the System Log viewer and it shows a large amount of the following line, usually around 30-40 times before overheating and shutting down.

ACPI-1041: ***Warning: Failed to acquire semaphore[dffe3640|1|0], AE_TIME

I also have a screenshot of the log viewer of one of those occurences, which can be seen here: http://briancurtin.com/images/var_log_messages_viewer.jpg

Contact me if anything else is needed on my part (brian DOT curtin AT gmail DOT com)

Additionally, is it known if SUSE 10 has this same, or similar, problem?

Comment 2 Thomas Renninger 2005-11-09 11:21:01 UTC

I cannot say whether these "Failed to acquire semaphore" messages influence that the laptop produces more heat. I even doubt it.

However we had some of these reports for 10.0 and it has finally been fixed there.
If your machine provides a passive trip point (cat /proc/acpi/thermal_zone/*/trip_points) your machine should not switch off anymore.

BTW: You can save energy consumption by rmmodding the ohci_hcd module if you don't use USB.
On some ATI mobility graphics card there is an option for xorg.conf like "DynamicClocks" "on" that also saves some power and heat production.

The patch is not yet in the mainline kernel..., watch this bug (should be added soon):
http://bugzilla.kernel.org/show_bug.cgi?id=3410

You opened the bug for 10.0 product, but specified the OS SL9.3, weird that this is even possible.

I expect that you opened the bug for 9.3, there this issue will probably not be fixed any more. For 10.1 (OpenSuse Alpha versions) this will automatically fixed as soon as the patch that has been included in 10.0 will be added to the mainline/vanilla kernel.
Please reopen if you should have problems with 10.0.

disregard that, it was applied to the wrong bug

Comment 5 Thomas Renninger 2005-11-18 08:04:14 UTC

Try to boot with ec_burst=0 boot param, do the cannot aguuire semphore messages vanish?
