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 model number: serial number: battery type: 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) @ 0x000fde64 Feb 28 11:28:48 ef kernel: ACPI: FADT (v001 DELL CPi R 10194.02588) @ 0x000fde90 Feb 28 11:28:48 ef kernel: ACPI: DSDT (v001 INT430 SYSFexxx 00000.04097) @ 0x00000000 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'? ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
