[OpenIndiana-discuss] ACPI errors

["Weiergräber, Oliver H."]

Hello,

while testing OpenIndiana (and Solaris 11) on an HP xw8600 workstation,
I noticed messages like this occurring regularly during bootup:

----------------------------------------------------------------------------------------------------------------------------

What kind of ACPI problem is indicated here? Anything to worry about? I did notice stability issues on Solaris 11, but not on OpenIndiana, so I guess these are unrelated to the ACPI stuff.
The BIOS version is the latest available for this machine.

Thanks in advance
Oliver
