RHBA-2010:0226 - Bug Fix Advisory

Topic

An updated iasl package that fixes a bug and introduces a feature
enhancement is now available.

Description

iasl compiles ASL (ACPI Source Language) into AML (ACPI Machine Language),
which is suitable for inclusion as a DSDT in system firmware. It also can
disassemble AML, for debugging purposes.

• the default version of iasl was old, and could not properly decode DMAR

tables. This sometimes resulted in incorrect decoding. Updating to the
latest version of the iasl package has corrected this behavior, and DMAR
tables are now decoded correctly. (BZ#518109)

• the iasl package has been updated to the latest version. (BZ#518209)

Users are advised to upgrade to this updated iasl package, which resolves
this issue.
