From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20031030 Description of problem: On my Fujitsu/Siemens Amilo D laptop, if I activate ACPI (using acpi=on in /etc/grub.conf) and CPU gets too hot, the keyboard becomes "sticky". That means, that keys keep repeating for a few second after you've stop pressing them. That happens with acpid running as well as with acpid stopped but it doesn't happen when acpi is disabled in the kernel. Tha bad news for you (but good news for me) is that I have fixed my CPU fan. So I can't reproduce the problem anymore because I can't reach the critical temperature (79 Celsius). Please see Bug #74635 for more information. Version-Release number of selected component (if applicable): kernel-2.4.22-1.2088.nptl How reproducible: Always Steps to Reproduce: 1.append "acpi=on" in /etc/grub.conf 2.break/remove your CPU fan 3.launch a CPU-using application (any compilation or video game) 4.wait until CPU temperature reaches the "critical" temperature (as stated by "cat /proc/acpi/thermal_zone/THR1/trip_points") 5.Try typing anything in a terminal Actual Results: Some letters will be repeated while you didn't intend to repeat them, giving sentences like: ttthiiiiis iss jjjjusssssttt a tesstttt... Expected Results: Nothing should happen. Additional info: Bug #74635 contains more information.
It's been a while sinc I had this bug, and it re-appeared today. And, actually, it was the first time since long that I used my laptop with the battery plugged in (I usually use it without the battery). After removing the battery, the bug disappeared.
so this happens only when 1. ACPI is enabled 2. battery is present 3. fan is broken and the temperature exceeds the critical shutdown temperature of 79C? pleaase capture the contents of the files under /proc/acpi/thermal_zone when this is happening, and when it is not happening. Can you verify that it still happnes with the 2.6-based FC2? thanks, -Len
Well, I've not been very complete in my last report. Here is exactly what I noticed: The "sticky keys" phenomenom appears when: - ACPI is enabled - temperature exceeds 79°C - the battery is plugged or un-plugged The new thing is that I saw it happen too when: - ACPI is *disabled* - the battery is plugged In the second case, I don't know what the temperature, because I don't know how to get such information without ACPI enabled. That said, I had been working for about 3 or 4 hours on my laptop (mostly programming involving compilation and, thus, heavy CPU usage) when it happened. So I guess the temperature was a bit high. Is there a way to get the temperature without ACPI ? Note that, maybe my laptop's temperature tends to grow faster when ACPI is off and the battery is plugged... that would explain why, when ACPI is off, it only happens with the battery plugged. But what's stranger is that removing the battery immediately made the bug go away, without rebooting or waiting for the laptop to "calm down"... For more information, I captured the files under /proc/acpi/thermal_zone during an intensive compilation session, *with ACPI on*: -- [root@localhost julien]# ls /proc/acpi/thermal_zone/* /proc/acpi/thermal_zone/THR1: cooling_mode polling_frequency state temperature trip_points /proc/acpi/thermal_zone/THR2: cooling_mode polling_frequency state temperature trip_points [root@localhost julien]# cat /proc/acpi/thermal_zone/*/* <not supported> <polling disabled> state: ok temperature: 61 C critical (S5): 78 C <not supported> <polling disabled> state: ok temperature: 53 C critical (S5): 72 C [root@localhost julien]# watch cat /proc/acpi/thermal_zone/*/* Every 2s: cat /proc/acpi/thermal_zone/THR1/cooling_...

But I know I have already tried a few 2.6-based fedora kernels a few months ago and the problem was still there, then I reverted to 2.4.
Still a problem in latest kernels ?
No, it seems fixed now. You can close it, thanks.
hi i have read all above conversation about repeating keys. I have the same problem after I upgrade from Redhat 8.0 to Fedora core 2, kernel 2.6 ofcourse. As said above, if turn acpi=off from grup.conf, the key repeating problem disappears, but sound card is undetected. Could you please help me out...ASAP. secondly could you add ravindrakrk, so that i can get reply. thanks
