From 9de1cc9c446d39546a3d9dd6f7d99a980a7ecc22 Mon Sep 17 00:00:00 2001 From: Fiodor Suietov Date: Tue, 19 Dec 2006 12:33:20 -0800 Subject: [PATCH] [PATCH] libata: wrong sizeof for BUFFER I have reproduced the AE_AML_BUFFER_LIMIT exception mentioned in basing on the SSDT ASL code and libata ata_acpi_push_id() code. There is an oversight in ata_acpi_push_id() causing the exception.
