Re: dmi info requested... - Dell - Precision WorkStation 690

[Len Brown <lenb@xxxxxxxxxx>]

Thanks for the acpidump.

It looks a lot like the Dell Precision M4300, but slightly simpler.

ISLI returns 1 for OSI(Linux). 0 for everything else.
GUSB is the only invocation of ISLI.

GUSB is invoked only on USB _INI, and on wakeup from hibernate.

So... If you notice any difference in USB function either
upon boot or resume from hibernate when using acpi_osi=Linux,
please let let us know.

thanks,
