Product: acpi
Component: libsasl2-plug-ntlm
Summary: some acpi modules not working on dell inspiron 8100
Version: 0.6-3mdk
Platform: PC
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: P2
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Laptop is a dell inspiron 8100 with latest (A14) bios + Mandrake-9.1 rc1 +
kernel-2.4.21.0.pre4.10mdk-1-1mdk.
No problems with acpi during install and the /proc/acpi entries for the
components compiled into kernel were all created.
Acpi modules had to be loaded by hand and some showed errors in
/var/log/messages such as:
Feb 28 11:47:22 ef kernel: ACPI: Battery Slot [BAT0] (battery absent)
Feb 28 11:47:22 ef kernel: ACPI-0188: *** Warning: Buffer created with zero
length in AML
Feb 28 11:48:22 ef kernel: ACPI: Thermal Zone [THM] (25 C)
Feb 28 11:49:32 ef kernel: ACPI-0188: *** Warning: Buffer created with zero
length in AML
Feb 28 11:49:32 ef kernel: -0072: *** Error: ut_allocate: Attempt to
allocate zero bytes
But all modules appear to be loaded:
# /sbin/lsmod
Module Size Used by Not tainted
thermal 8224 0 (unused)
fan 2528 0 (unused)
button 3724 0 (unused)
processor 10872 0 [thermal]
ac 2816 0 (unused)
battery 7008 0 (unused)
All entries for the modules are also created in /proc/acpi but not everything
is working, for example the battery.
When the laptop is connected to a power outlet:
# cat /proc/acpi/ac_adapter/AC/state
state: on-line
# cat /proc/acpi/battery/BAT1/state
present: yes
capacity state: ok
charging state: unknown
present rate: 0 mA
remaining capacity: 0 mAh
present voltage: 0 mV
When the laptop is running on the battery:
# cat /proc/acpi/ac_adapter/AC/state
state: off-line
# cat /proc/acpi/battery/BAT1/state
present: yes
capacity state: ok
charging state: unknown
present rate: 0 mA
remaining capacity: 0 mAh
present voltage: 0 mV
Also 'info' under /proc/acpi/battery/BAT1 appears to be 'dead':
# cat /proc/acpi/battery/BAT1/info
present: yes
design capacity: 0 mWh
last full capacity: 0 mWh
battery technology: non-rechargeable
design voltage: 0 mV
design capacity warning: 0 mWh
design capacity low: 0 mWh
capacity granularity 1: 0 mWh
capacity granularity 2: 0 mWh

OEM info:
Judging from the entries in /var/log/messages the Dell ACPI BIOS appears
to be ok. At least it says 'ACPI BIOS passes blacklist':
Feb 28 11:28:48 ef kernel: ACPI: RSDP (v000 DELL ) @
0x000fde50
Feb 28 11:28:48 ef kernel: ACPI: RSDT (v001 DELL CPi R 10194.02588) @

Feb 28 11:28:48 ef kernel: ACPI: BIOS passes blacklist
Feb 28 11:28:48 ef kernel: ACPI: MADT not present
Feb 28 11:28:48 ef kernel: Dell Inspiron with broken BIOS detected. Refusing to
enable the local APIC.
Can the broken APIC have anything to do with it?
Should I report these problems 'upstream'?
