Summary: i386 NUMA does not work on non x440/Summit Kernel Version: 2.5.68 Status: NEW Severity: normal Owner: mbligh@aracnet.com Submitter: ak@suse.de
When a summit CONFIG_DISCONTIGMEM kernel is booted on a non summit/numa 4cpu box it'll not boot, hanging before console init
Enabling early printk shows that it gets to the numa memory init and then dies with an endless "unknown interrupt" loop.
Looks like the srat discontigmem init fallback path does not work.
This is also a problem with the dynamic subarchitecture path (only in -mm) when CONFIG_NUMA is enabled. It disallows to build a generic generic CONFIG_NUMA kernel.
