Summary|2.6.16.16 and Pentium D dies|2.6.16.16 boot hang in ACPI
|at boot in ACPI |mode, 2.6.12 boots 1 of 2
| |processors - Pentium D
------- Additional Comments From [EMAIL PROTECTED] 2006-05-18 00:39 -------
There are two problems here:
1. 2.6.12/Knoppix boots in ACPI mode, but enables only 1 processor?
The BIOS is not enabling the 2nd processor:
Linux version 2.6.12 ([EMAIL PROTECTED]) (gcc-Version 3.3.6 (Debian 1:3.3.6-7))
#2
SMP Tue Aug 9 23:20:52 CEST 2005
...
ACPI: LAPIC (acpi_id[0x01] lapic_id[0x00] enabled)
Processor #0 15:6 APIC version 20
ACPI: LAPIC (acpi_id[0x02] lapic_id[0x01] disabled)
ACPI: LAPIC (acpi_id[0x03] lapic_id[0x82] disabled)
ACPI: LAPIC (acpi_id[0x04] lapic_id[0x83] disabled)
Update your board with the latest BIOS from the vendor,
then go into SETUP and make sure there is no option
that is turning off the 2nd processor.
2. 2.6.16.16 ACPI-mode boot hang:
Please always add "debug" to the cmdline.
the "acpi=off" dmesg is missing some lines.
Is it possible to capture the serial console log of
the failure with just "debug" as a parameter?
Also, try booting with "noapic".
If there is something funky about the timer IRQ on this board
that 2.6.16 is tripping over, this should get around it and
run in legacy PIC mode just like the "acpi=off" case does.
