Bug Description
Although it was closed and a patch released, bug 147560(https:/
While running without the acpi=noirq kernel parameter, the battery erroneously disappears.
The battery is detected during boot:
$ dmesg | grep battery
[ 12.305116] ACPI: Battery Slot [BAT1] (battery present)
and appears to work fine for a while:
$ cat /proc/acpi/
present: yes
design capacity: 4400 mAh
last full capacity: 3255 mAh
battery technology: rechargeable
design voltage: 10800 mV
design capacity warning: 0 mAh
design capacity low: 0 mAh
capacity granularity 1: 1 mAh
capacity granularity 2: 1 mAh
model number: MS-1719
serial number:
battery type: LION
OEM info: MSI Corp.
$ cat /proc/acpi/
present: yes
capacity state: ok
charging state: charged
present rate: 0 mA
remaining capacity: 3255 mAh
present voltage: 12506 mV
$ acpi -bs
Battery 0: Full, 100%
But after ~10 minutes, it disappears
$ cat /proc/acpi/
present: no
$ cat /proc/acpi/
present: no
$ acpi -bs
[nothing]
I receive similar results WITH the acpi=noirq kernel parameters, except it will take ~1-2 hours before the battery disappears. Problem persists whether or not the AC power is plugged in.
When I boot into Ubuntu 8.10, kernel 2.6.27-9-generic, the acpi=noirq kernel parameter works and I never lose the battery. Please let me know what other information I can provide or if you need someone to test out patches, I would be willing to do so.

Because this got moved to the acpi section, I've included the standard information.
