Averatec laptop- acpi_power_off hang

Averatec laptop- acpi_power_off hang

[JP Mercury]

Hi everyone,

I first posted to the list in December when I was having some trouble getting
an  Averatec 3250 laptop to report temperature. Thanks to Zhenyu Wang, that
problem was cleared with a change to my DSDT (scoping problem). 

Now I'd like to tackle the stubborn problem of powering off. Linux shuts down
but after acpi_power_off is called, it hangs. I tried the noapic, nolapic
kernel options as suggested for some other laptops- no go. Now I'm wondering,
could this be another DSDT problem? 

Here's my disassembled DSDT:
http://home.graffiti.net/swirlee/acpi-dsdt.dsl

There's also a problem with this laptop with other sleep states-- for example,
S3 seems to suspend (screen goes off, fans power down, power light flashes,
etc)  , but when I press a key the system reboots instead of resuming.

Any insight is much appreciated.

Thanks,
-Jan

did you also try it without RTC? There was something with the
realtimeclock that might prevent a power-off, if I remeber correctly.

Without RTC seems to make no difference.

Thanks for your suggestion.
