From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040518 Firefox/0.8 Description of problem: Tyan K8W system, 4GB memory, BIOS v2.02 RHEL 3 U2, kernel version 2.4.21-15.0.3.ELsmp SRAT/NUMA is setup in the BIOS, but RHEL is unable to setup NUMA when loading the kernel. I've attached the messages file to help. See these lines: Jul 8 13:24:31 testpig3 kernel: kernel direct mapping tables upto 10280000000 @ 8000-13000 Jul 8 13:24:31 testpig3 kernel: Scanning NUMA topology in Northbridge 24 Jul 8 13:24:31 testpig3 kernel: Node 0 MemBase 0000000000000000 Limit 000000017fffffff Jul 8 13:24:31 testpig3 kernel: Node 1 MemBase 0000000180000000 Limit 000000027fffffff Jul 8 13:24:31 testpig3 kernel: Node map not sorted 180000000,0 Jul 8 13:24:31 testpig3 kernel: No NUMA configuration found Jul 8 13:24:31 testpig3 kernel: Faking a node at 0000000000000000-0000000280000000 I have tried numa=on at the boot prompt as a kernel option, but that doesnt make a difference, since NUMA is running, it just seems like its having a problem sorting. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Bootup the computer Actual Results: It boots up normally, but you get this nice message in /var/log/messages Expected Results: It should say that it found a NUMA configuration and it initialized normally. Additional info:
This looks suspiciously like another issue I've seen; will investigate.
I checked, and this should be fixed in Update 3. The node-detection code has been modified to better identify and skip nonexistent node table entries.
Ok, is there a package in the beta channel that I can hand the customer until the next release, or is it in the kernel package. If its in the kernel package I'll just tell him to wait till next release.
It's a kernel fix. Grab the kernel from the beta channel and give it a try.
Jim closed this as being fixed in "next release", which would normally refer to RHEL4. But the bug is actually being fixed in RHEL3 Update 3, and it was tracked in bugzilla #121708. So I'm (re)closing this as a dup of the older bug. -ernie *** This bug has been marked as a duplicate of 121708 ***
