10.04 beta1 hangs on switch to battery // ACPI PROBLEM // maybe kernel Problem

[mario appinger]

On mains power it works fine but when I either switch to battery or attempt to boot on battery it hangs.

cant figure out wat is causing the crash -

also tried nolapic noapic noacpi and nosmp - does not change anything

i have seen some errors on gnome power management in launchpad - where they say that the battery isn't detectet - but i dont thinkt that the machine wont to suspend - and cat /proc/acpi/battery/BAT0 is recognized correctly

i have no idea how to find out what is causing the problem - maybe anyone can help here

iam using 10.04 beta 1 latest kernel (Linux map-noapple 2.6.32-17-generic #26-Ubuntu SMP Sat Mar 20 02:23:45 UTC 2010 x86_64 GNU/Linux)

by the way - this also effects the "recovery" Bootmode...

greetings from vienna,AT

i will report anything i can = o)

Can you provide hardware details? I work off of my Thinkpad all the time, and would definitely have noticed this if it effected me.

more detail - it also happens booting 10.04 beta1 live cd - just plugging of the ac adapter an the maschine freezes - also tried to watch kern.log, messages, syslog, Xorg.log while disconnecting the ac adapter - no line is written...

this behavier is 100% reproducible ...still i have no idea how to find out what happens

[mario appinger (mario-appinger)]

dont know what that means "tags: added: kernel-series-unknown "but...

2.6.32-17-generic #26-Ubuntu SMP Sat Mar 20 02:23:45 UTC 2010 x86_64 GNU/Linux) is the kernel = o)

[mario appinger (mario-appinger)]

I'm not sure if this is really the same issue https://bugs.launchpad.net/ubuntu/+source/linux/+bug/272247

i will try out the hotfix with acpi=noirq and will report the result within the next 4 hours

[mario appinger (mario-appinger)]

definitely the kernel options like acpi=noirq and noacpi nolapic noapic does not change anything

[mario appinger (mario-appinger)]

sorry - i have tried it again - and recognized that i have to boot via acpi=off then i can boot - but this is not a fine solution running on a notebook - because my fan is running at highest level.....

now i wanna ask - is this a kernel bug or a acpi subsystem bug????

[Hermann Dorfinger (fnorded)]

I can reproduce this on a Lenovo Thinkpad x100e

Disconnecting the AC Power freezes the system.
Booting on battery power works until the login screen, then freezes as well.
Setting acpi=off at boot time didn't work the first time I tried a few days ago but i will retest that.

Toggling display brightness via hotkeys or power manager freezes the system as well, but i think that has something to do with thinkpad_acpi not yet supporting the x100e model ("not yet supported thinkpad detected")

[Hermann Dorfinger (fnorded)]

tests today were kinda surprising. after doing the upgrades from the last few days it's working now.
no more lockups when disconnecting ac power or toggling the display brightness.
