[Bug 727628] New: IBM Thinkpad T420: screen black in agrressive powersave mode / unhandled ACPI-request
https://bugzilla.novell.com/show_bug.cgi?id=727628 https://bugzilla.novell.com/show_bug.cgi?id=727628#c0 Summary: IBM Thinkpad T420: screen black in agrressive powersave mode / unhandled ACPI-request Classification: openSUSE Product: openSUSE 11.4 Version: Final Platform: x86-64 OS/Version: openSUSE 11.4 Status: NEW Severity: Major Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: p.heinlein@heinlein-support.de QAContact: qa@suse.de Found By: --- Blocker: --- I'm using a new Thinkpad T420 laptop with SandyBridge with OpenSUSE 11.4 and OpenSUSE ThumbleWeed with KDE. If the battery is empty and the system is in aggressive powersave mode, the screen becomes black if I plug in the power cable. Looks like the system is still working, but the screen is shut down. Even when changing to tty1 or when changing back to tty7/KDE, the screen remains black and unusable. With dmesg I saw this errors: [ 300.752879] [Hardware Error]: Machine check events logged [ 307.790734] thinkpad_acpi: unknown possible thermal alarm or keyboard event received [ 307.790760] thinkpad_acpi: unhandled HKEY event 0x6040 [ 307.790762] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@lists.sourceforge.net [ 307.792318] thinkpad_acpi: EC reports that Thermal Table has changed => Major bug, because it's not possible to work on the laptop if agressive powersave mode has already been reached. The system has to be rebooted after the power cable has been attached. Data loss is possible! I'll alert this to ibm-acpi-devel@lists.sourceforge.net. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I ever came across some BIOS implementation that notifies acpi display switch event (via Notify (VGA, 0x80/0x81)) while plug/unplug AC power or open/close lid. Takashi had a patch that tried to circumvent it with a module param but unfortunately it's seems not get mainlined eventually. http://www.spinics.net/lists/linux-acpi/msg30706.html -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

OOPS. It cannot simply check by rmmod video as i915 requires it. We have to find other way. :/ -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

If not please do so. This may already have been addressed mainline.
I'll alert this to ibm-acpi-devel@lists.sourceforge.net Has there been any outcome yet? Possibly google knows more about this problem now, Thinkpad/Lenovo Linux community is big.
If this still exists in 12.2, please also increase acpi debug output a bit (not too much or you get tons of output lines in dmesg). acpi.debug_level=0xF acpi.debug_layer=0xFFFFFFFF These boot parameters should be sufficient to get all ACPI notify events logged into dmesg. Are we sure already this is due to video and not thinkpad_acpi driver events? And if which events exactly are happening? -> This test should find out about it. Above boot parameters can also be modified at runtime (to avoid too much output at booting) via: echo 0xF >/sys/module/acpi/parameters/debug_level echo 0xFFFFFFFFF >/sys/module/acpi/parameters/debug_layer You may want to attach a whole dmesg with enhanced debug options. For better readability, additional extraction of the events and debug messages when the problem occurs would help. Maybe you can log in via ssh if the problem happens and get it: tail -n 100 /var/log/messages >screen_gone_debug.txt scp screen_gone_debug.txt <other_host>:/tmp -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

For sure it's not possible to stop one year working and wait for help. I already changed my hardware and bought a new notebook several month ago. I can't check and help in this case any more and I'm not interested in this bug any more. As often in SUSE's bugzilla: Just wait long enough for month and year's and the problem has solved itself by people creating their own workarounds.

As often in SUSE's bugzilla: Just wait long enough for month and year's and the problem has solved itself by people creating their own workarounds. We cannot solve the whole worlds platform specific bugs. If you want someone to explicitly work on your HW specific issues within some days, you have to buy a SLED. If you have a suitable workaround or even a solution for example from ibm-acpi-devel@lists.sourceforge.net which makes sense to add to our distribution, tell us and we would certainly add it.
If the problem still exists on 12.2 and someone else can provide info from comment #7 or could already point to a solution that makes sense to integrate, please reopen. Noresponse in this case means no response can be given, because the reporter does not have the HW anymore. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
