[issue2003] acpica upgrade to 20110211 (again)

[Magliano Andrea]

Hi Sepherosa,

got some additional information (hope it helps).

After this hunk (from fbsd) the overrall system reaction is ok (say, like no loading of acpi.ko)

I tried booting a kernel with same debug level (events+function), but without the acpi code upgrade and i have an interrupt storm as well...

kernel bootlog with no acpi upgrade (i.e. acpi 20090521):

   evsci-0154 [136] EvSciXruptHandler     : ----Entry
 evevent-0309 [136] EvFixedEventDetect    : Fixed Event Block: Enable 00000120 Status 00000011
   evgpe-0525 [136] EvGpeDetect           : Read GPE Register at GPE08: Status=00, Enable=02
   evsci-0175 [136] EvSciXruptHandler     : ----Exit-        0       0

kernel bootlog with acpi upgrade:

   evsci-0154 [136] EvSciXruptHandler     : ----Entry
 evevent-0297 [137] EvFixedEventDetect    : ----Entry
 evevent-0309 [137] EvFixedEventDetect    : Fixed Event Block: Enable 00000120 Status 00000011
 evevent-0336 [137] EvFixedEventDetect    : ----Exit-        0       0
   evgpe-0525 [136] EvGpeDetect           : Read GPE Register at GPE00: Status=00, Enable=01
   evgpe-0525 [136] EvGpeDetect           : Read GPE Register at GPE08: Status=00, Enable=0E
   evsci-0175 [136] EvSciXruptHandler     : ----Exit-        0       0

the GPE registers may be interpreted in a different way in the new acpi release, but GPE00 register is now seen...
