Did you determine that the buffer overrun problem that caused the slab corruption was the same thing that caused the unaligned access messages? Can you point me to the patch? Or possibly a place to get the 20060217 ACPICA and the previous version, so I can extract the patch myself? I poked around the Intel ACPI web page, but could only find the most recent ACPICA; there didn't seem to be any history.
