You are still getting > another panic that I'm not sure how to fix. *hmm* while this is true w/o ACPI enabled with ACPI enabled I do not get a panic while booting a kernel prior to this commit (which is equal to the patch you had sent me). With your patch (thus also with this commit I guess) I do get the panic with and without ACPI. Conclusion: with this patch/commit I will no longer be able to boot this problematic machine here.
