_OSI boot hang

_OSI boot hang

[Len Brown]

_OSI is in the ACPI patch on kernel.org and bkbits right now.

However, I find that on my Toshiba Satellite Pro, it causes boot to hang
at Executing all Device _STA and_INI methods.

>From ACPICA, it comes this way:
drivers/acpi/utilities/utglobal.c
const char                         
*acpi_gbl_valid_osi_strings[ACPI_NUM_OSI_STRINGS] = {
                       "Linux",
                       "Windows 2000",
                       "Windows 2001",
                       "Windows 2001.1"};


I find that it is the match on "Windows 2001" that hangs my laptop...

clues?

Hmmm, now my Toshiba is not hanging.  Maybe the hang wasn't related to
_OSI afterall?

In any case, if you experience issues with the latest
"acpi_osi=" or "acpi_serialize" may be helpful -- do speak up if you
find they're necessary.

thanks,

That's not the right string for Win2k.  It's:
  "Microsoft Windows NT"

Since this is the most popular string, not emulating it is probably
causing some people problems.

Not according to the MS white paper on OSI.

Yes, \_OS used strings like "Microsoft Windows NT", but apparently not
OSI

You're correct.  On a second check, I only found Windows 2001 and above in
terms of ASL checking for OSI strings.
