[OpenIndiana-discuss] ACPI errors

["Weiergräber, Oliver H."]

Hello,

just a quick follow-up on this issue: These ACPI errors are still present both with oi 151a7 and Solaris 11.1.
Since I observed a similar message with CentOS 6 (and, by inference, RHEL 6) but not with earlier linux versions, I issued a bug report with them,
and got this useful hint:

"HP's firmware doesn't like _OSC being called multiple times. This is a violation of 6.2.10 of the ACPI specification, but was worked around in upstream commit 415e12b2379239973feab91850b0dce985c6058a"

This "commit" can be found here: 
http://git.opencores.org/?a=commit&p=linux&h=415e12b2379239973feab91850b0dce985c6058a

I hope this helps to get a fix (or workaround) into OpenIndiana ACPI.

Best regards,
Oliver

Hi Olivier,

OK, so you are on the latest OI ACPI, 20110527, the issue found by Dana
was fixed already. It looks like some different bug. I have to look at
it but it is some time I was working on Solaris ACPI so I need to
refresh my knowledge. I will inform you about progress if there will be
some. In parallel somebody else is trying to update Illumos ACPI to the
newer versions, maybe it will help.

Best regards,

Milan

There are (and have been) a few bug reports for RHEL and other linux distributions, often concerning HP workstations (as in my case). Looking into https://www.acpica.org/download/changes.txt it appears that this issue is mentioned in the release notes from 12 January 2011:
