Thread-topic: Numa=on broken?

All, It looks like numa=on is broken. I have tried with the tip of the tree, with the changeset 14676 (which fixes the numa=on problem) and the two patches that Ryan sent out. I am running with boot options acpi=on and numa=on. I am running on an ES7000 with 2 nodes (2 cells of 8 processors and 32 GB memory each). Thanks Raj PS. We(Unisys) are going to start running our weekly tests with default numa=on. This weeks' tests brought out this problem. \ \/ /___ _ __ |___ / / _ \ _ _ _ __ ___| |_ __ _| |__ | | ___ \ // _ \ '_ \ |_ \| | | |__| | | | '_ \/ __| __/ _` | '_ \| |/ _ \ / \ __/ | | | ___) | |_| |__| |_| | | | \__ \ || (_| | |_) | | __/ /_/\_\___|_| |_| |____(_)___/ \__,_|_| |_|___/\__\__,_|_.__/|_|\___| http://www.cl.cam.ac.uk/netos/xen University of Cambridge Computer Laboratory Xen version 3.0-unstable (root@site) (gcc version 4.1.2 20070115 (prerelease) (SUSE Linux)) Thu May 3 16:58:28 EDT 2007 Latest ChangeSet: Thu May 03 11:22:58 2007 +0100 15007:c857bf38f015 (XEN) Command line: /boot/xen.gz com1=115200,8n1 apic_verbosity=debug dom0_mem=512M acpi=on numa=on (XEN) 0000000000000000 - 000000000009d000 (usable) (XEN) 000000000009d800 - 00000000000a0000 (reserved) (XEN) 00000000000ce000 - 0000000000100000 (reserved) (XEN) 0000000000100000 - 0000000037e70000 (usable) (XEN) 0000000037e70000 - 0000000037ed8000 (ACPI data) (XEN) 0000000037ed8000 - 0000000037f00000 (ACPI NVS) (XEN) 0000000037f00000 - 00000000f0000000 (usable) (XEN) 00000000f8000000 - 00000000fec00000 (reserved) (XEN) 00000000fffc0000 - 0000000100000000 (reserved) (XEN) 0000000100000000 - 0000001008000000 (usable) (XEN) System RAM: 65407MB (66976820kB) (XEN) Cannot handle page request order 0!
