Please confirm that this smaller one resolves your problem. carenas@sajinet.com.pe 2006-04-28 23:56:35 0000 proposed patch confirmed to work. i agree that a proposed fix shouldn't apply the full patch, but only the following snippet (composed mostly of formatting and other null changes) from that patch : file:a95f636dc35d454e16865732cff8e4c57ab3731f -> file:71e7769d7dafcf66653cbb0d9ebb0f9e34c9b9c7 and obtained by doing (attached, even if i keep thinking there should be an easier way to get it) mkdir -p ~a/drivers/acpi/namespace git-cat-file blob a95f636dc35d454e16865732cff8e4c57ab3731f > ~/a/drivers/acpi/namespace/nsxfeval.c mkdir -p ~/b/drivers/acpi/namespace git-cat-file blob 71e7769d7dafcf66653cbb0d9ebb0f9e34c9b9c7 > ~/b/drivers/acpi/namespace/nsxfeval.c cd diff -urp a b > acpica-20060210-nsxfeval.patch rm -rf a b or the corresponding snippet from that patch (attached as acpica-20060210-nsxfeval-debug.patch), and this way preventing future merge conflicts or divergent code from upstream. sadly on that line, confirmed with Len (the Linux ACPI maintainer) that this patchset won't be merged upstream until 2.6.18 the least. carenas@sajinet.com.pe 2006-04-28 23:58:02 0000 Created an attachment (id=85733) nsxfeval.c changes as part of acpica-20060210 carenas@sajinet.com.pe 2006-04-28 23:59:02 0000 Created an attachment (id=85735) snippet from nsxfeval.c changes part of acpica-20060210 dsd@gentoo.org 2006-04-29 04:02:44 0000 We'll only take whats necessary, the larger patch contains other code changes (and actually would increase the chance of conflict).
