Hello, As the summary line suggests, vanilla kernel version 3.0.3 does not generate ACPI events on the Sony Vaio VPCS12X9E when the AC adapter is plugged/unplugged. Currently, Kubuntu 11.04 is installed on this machine. The stock kernel that comes with Kubuntu 11.04, version 2.6.38, also exhibits the same problem, so I am assuming that this problem is not a regression. As suggested by [1], I am going to attach the following information to this bug report: - acpidump output - dmesg output after a clean boot - dmesg output after the following: # dmesg -c # echo 0x04 > /sys/module/acpi/parameters/debug_layer # echo 0x8800001f > /sys/module/acpi/parameters/debug_level plug/unplug the AC adapter Thank you, Mehmet Vefa Bicakci [1] http://marc.info/?l=linux-acpi&m=119517666909485&w=2
Created attachment 70362 [details] acpidump Output generated by acpidump
Created attachment 70372 [details] dmesg output after a clean boot with kernel version 3.0.3
Created attachment 70382 [details] dmesg output after the mentioned test To produce this output, the following actions were taken with kernel 3.0.3: # dmesg -c # echo 0x04 > /sys/module/acpi/parameters/debug_layer # echo 0x8800001f > /sys/module/acpi/parameters/debug_level - run "yacpi" - unplug AC adapter - refresh display of "yacpi" - plug in AC adapter - refresh display of "yacpi" I should also note the following: In order to generate the events in dmesg, I had to run the "yacpi" utility and after unplugging/plugging in the AC adapter, I had to refresh the "yacpi" utility's display. "yacpi" reads its information from /proc. If I do not refresh "yacpi"'s display after taking plugging/unplugging the AC adapter, then the kernel does not generate ACPI events.
Created attachment 70392 [details] dmesg output after the corrected test I just realized that I had not set the debug_level parameter of the acpi kernel module properly before carrying out the test. I am attaching the dmesg output after the steps mentioned below have been carried out. I should also note that this time I did not need to use "yacpi". # dmesg -c # echo 0x04 > /sys/module/acpi/parameters/debug_layer # echo 0x8800001f > /sys/module/acpi/parameters/debug_level - unplug AC adapter - plug in AC adapter The timing is as follows: - 624 seconds after boot, the AC adapter was unplugged. - 643 seconds after boot, the AC adapter was plugged in.
how do you know it does not generate any ACPI event? please attach the output of "grep . /sys/firmware/acpi/interrupts/*" both before and after plugging/unplugging the AC adapter.
Please run acpi_listen during plugging or unplugging AC adapter to scratch ACPI event.

ps: i'm on kernel 3.3-rcX now. Also on kernel 2.6.39 - 3.0.X - 3.1.X - 3.2.X i've this problem!
From the DSDT table, I don't see the AC adapter device gets notified anywhere, so I don't think there is any chance for the kernel to capture such events if firmware(acpi) does not support it.
