Description Gurkan Vural 2005-10-04 11:51:00 UTC

Most recent kernel where this bug did not occur: N/A
Distribution: Gentoo
Hardware Environment: MSI 510C
Software Environment:
Problem Description: No battery or ac event can be received from
/proc/acpi/event. However their status are updated correctly in
/proc/acpi/ac_adapter/ADP1/state and /proc/acpi/battery/BAT1/state.

Steps to reproduce:

Comment 1 Gurkan Vural 2005-10-04 11:55:09 UTC

Below is simple /proc/acpi/battery/BAT1/state and
/proc/acpi/ac_adapter/ADP1/state outputs:

/proc/acpi/battery/BAT1/state
present:                 yes
capacity state:          ok
charging state:          discharging
present rate:            1105 mA
remaining capacity:      1516 mAh
present voltage:         14831 mV

/proc/acpi/ac_adapter/ADP1/state
state:                   off-line

and after plugging AC adapter:

/proc/acpi/battery/BAT1/state
present:                 yes
capacity state:          ok
charging state:          charging
present rate:            2582 mA
remaining capacity:      1478 mAh
present voltage:         15538 mV

/proc/acpi/battery/BAT1/state
state:                   on-line

dsdt

Comment 5 Len Brown 2005-10-06 21:20:03 UTC

is this a regression, or have older kernels behaved the same way?

Comment 6 Gurkan Vural 2005-10-06 23:51:20 UTC

I think the problem is in dsdt. It notifies ac adapter events as 0x00 not 0x80.
Also battery notification value is different from the kernel code
drivers/acpi/battery.c.

Bus/device events are added to ac./battery notification.

Please try this patch, send the results of ac/battery plugging/unplugging and
dmesg output.
