My system is an Abit VP6 with two 1GHz Pentium III processors, running Red Hat Linux/Fedora Core. One of the kernel updates to Red Hat 9 messed up APIC-based interrupt routing on this board, causing USB devices to not be recognized. (See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=92417.) So I was pretty happy when one of the Fedora core test releases was able to boot with ACPI turned on and recognize USB devices. Fedora Core 1, however, panics when I boot with 'acpi=on'. I have traced this regression to the fact that CONFIG_DEBUG_SLAB was turned on in the test release kernel, but it's off in the "production" kernel. The question is, where do I go from here? The help for CONFIG_DEBUG_SLAB makes it seem unlikely that this is the root cause, but I don't have any idea how I can debug this further. TIA for any help. -- ======================================================================== Ian Pilcher i.pilcher-Wuw85uim5zDR7s880joybQ@public.gmane.org ======================================================================== ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
