Description Carlo Marcelo Arenas Belon 2008-07-12 11:22:48 UTC

iasl is not 64bit clean code and could in some cases (as shown by the linked BUG report be miscompiled enough to result in a segfault for perfectly working ASL.

the version currently reported as stable doesn't show the problem, and neither does the last release from upstream so this problem could be fixed by either hard masking the current unstable ebuild, or bumping it to the 20080701 version.

Reproducible: Always

Steps to Reproduce:
1. edit the KVM ebuild to re-enable the BIOS use flag
2. USE="bios" emerge -Dv kvm
3.

Actual Results:  
iasl -tc -p acpi-dsdt.hex acpi-dsdt.dsl.i
