Version-Release number of selected component (if applicable): Linux willow.rchland.ibm.com 2.6.9-55.EL #1 SMP Fri Apr 20 16:33:09 EDT 2007 ppc64 ppc64 ppc64 GNU/Linux How reproducible: Steps to Reproduce: 1. boot the first partition make sure it is up and running 2. then boot the default rhel4 kernel on the second partition 3. Once the second partition is up use 'dmesg' to see the cpu stuck message Actual results: Expected results: Additional info: Bug does not exist in upstream kernels.

Created attachment 248661 [details] Revert hunk of linux-2.6.9-ppc64-rpacc.patch to use (correct) logical CPU ID pseries_secondary_smp_init() expects to recieve logical CPUIDs, this patch part of linux-2.6.9-ppc64-rpacc.patch mistakenly passes the hardware IDS. Revert that hunk to put things right. Without this patch machines where phys_id != logical_id will (at best) fail to bring up all CPUS This patch applies on top of CPU spinup debug/fixup patch. Tested on a POWER4+ machine with 2 LPARS, LPAR1 has cpus 0-17, LPAR2 has cpus 18,19. Both LAPRS boot with all CPUS with patch. Without LPAR2 only ens up with one functional CPU. This is RH Issue 136494
After a quick look at the current 2.6.18 git tree, it does not appear this patch is currently upstream: A) Has it been posted for upstream inclusion (please provide lkml link or commit # if indeed it is) B) Should it be?
