Summary: Sony Vaio VPCS12X9E: Plugging/unplugging the AC
adapter does not generate ACPI events
Product: ACPI
Version: 2.5
Kernel Version: 3.0.3
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Config-Interrupts
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No
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
