           Summary: ACPI Hangs on Boot
           Product: ACPI
           Version: 2.5
     KernelVersion: 2.6.23.12
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


Most recent kernel where this bug did not occur: NA on this hardware
Distribution: LinuxMint 4.0
Hardware Environment: Acer 4520 (all stock)
Software Environment: Dual-Boot with Vista
Problem Description:  Kernel hangs on boot at:

ACPI: EC: GPE = 0x10, I/O: command/status = 0x66, data = 0x62

Steps to reproduce:

I custom compiled the kernel to solve another ACPI issue which I may file a bug
report for later.   I will try with apci=off momentarily.

Oddly enough, when the power button is pressed, the kernel resumes booting and
runs as normal! 


acpi=off results in a kernel panic telling me to run with noapic, running with
noapic results in it telling me that I need to run with pnpbios=off.   

Finally, if I boot with "acpi=off noapic pnpbios=off" it hangs at loading my
DVD-ROM, after about 5 minutes it will give an error dealing with a lack of a
root file system, (no /dev/sda5).

This is the latest kernel, so this should be fixed, unless I did something
stupid compiling it, then I should be fixed. :-P

Regardless, there have been similar errors on the two stock kernels that
shipped with LinuxMint, the 2.6.22.14-generic fails to boot entirely (power
button trick doesn't work) and 2.6.22.14-386 works with power button trick,
albeit at a different point in the boot sequence.

Thanks,
Dan O.
