Of course :)

2.6.0 plus your above patch yields a very similar panic, though not
 100% identical.

* EIP is at the same place
* Call trace is missing delay_tsc, otherwise identical, offsets included
* First three blocks of the stack differ (all the rest looked identical)
* There is no "VLI" string after "Not Tainted" (I assume it's another
   part of the -mm1 patch)

So yup, you got the part that makes -mm1 unbootable here :)

Here's my ACPI options:

[asuardi@incident linux]$ grep -i acpi .config
# Power management options (ACPI, APM)
# ACPI (Advanced Configuration and Power Interface) Support
CONFIG_ACPI=y
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_INTERPRETER=y
# CONFIG_ACPI_SLEEP is not set
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
# CONFIG_ACPI_BUTTON is not set
CONFIG_ACPI_FAN=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_THERMAL=y
# CONFIG_ACPI_ASUS is not set
# CONFIG_ACPI_TOSHIBA is not set
CONFIG_ACPI_DEBUG=y
CONFIG_ACPI_BUS=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SYSTEM=y
# CONFIG_ACPI_RELAXED_AML is not set
CONFIG_X86_ACPI_CPUFREQ=y
# CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set
# CONFIG_SERIAL_8250_ACPI is not set

Available for any fiddling. Ah, holidays ;)


Thanks, ciao,
