From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050317 Firefox/1.0.2 Description of problem: Using a Dual Opteron on a Tyan S2880 motherboard and 6 2GB DIMMS only 8GB is seen by the kernel. On FC3 all the memory is seen and used but upgrading to FC4 only 8GB is seena and used. Something must have changed in 2.6.11. Version-Release number of selected component (if applicable): kernel-smp-2.6.11-1.1369_FC4 How reproducible: Always Steps to Reproduce: 1.Load FC4 2.Use the FC4 kernel on FC3 3. Actual Results: Only 8GB is used Expected Results: Should see all 12GB of memory Additional info:
I tried the new 2.6.12 kernel from development Linux version 2.6.12-1.1400_FC5smp (bhcompile@crowe.devel.redhat.com) (gcc version 4.0.0 20050622 (Red Hat 4.0.0-13)) #1 SMP Thu Jun 23 23:32:58 EDT 2005 And I still have the same problem Memory: 8106892k/12582912k available (2459k kernel code, 0k reserved, 1307k data, 228k init) I am not sure whether to look at the Tyan Motherboard or if I should download the Kernel source and compile. Does RedHat put a limit in the Fedora Kernel at 8GB?
There are no such restrictions on memory (or other resources) in the Fedora kernel. Can you attach the output of dmesg -s 128000 please ?

Your BIOS has a buggy SRAT table.. SRAT: Node 1 PXM 1 200000000-2ffffffff This line tells us that there is 4GB at that address, but according to the e820 table.. BIOS-e820: 0000000100000000 - 0000000300000000 (usable) there's really 8GB there. Nothing we can do here, you'll have to complain to your motherboard vendor to fix their BIOS. (Or possibly try changing options in the BIOS related to SRAT/NUMA if there are any at all).
Sorry I wasted yout time, but I looked for a problem like that and it seems to have no problem seeing all 12GB with the FC3 2.6.10 Kernel.
Oops, sorry, I misread your report. Ok, that's clearly a regression somewhere. I'll look into it.
Can you attach the dmesg of the kernel that works so we have something to compare ?
Created attachment 116055 [details] kernel 2.6.10 FC3 This is the log from 2.6.10 on FC3
Created attachment 116056 [details] 2.6.11 FC4 kernel This is the log from the stock FC4 kernel
Created attachment 116119 [details] the 2.6.10 and 2.6.11 I reboted with the 2.6.10, then the 2.6.11 today and enclosed both logs.
I tried the new 2.6.12.2 kernel today and the same thing.

[This comment has been added as a mass update for all FC4 kernel bugs. If you have migrated this bug from an FC3 bug today, ignore this comment.] Please retest your problem with todays 2.6.12-1.1398_FC4 update. If your problem involved being unable to boot, or some hardware not being detected correctly, please make sure your /etc/modprobe.conf is correct *BEFORE* installing any kernel updates. If in doubt, you can recreate this file using.. mv /etc/sysconfig/hwconf /etc/sysconfig/hwconf.bak mv /etc/modprobe.conf /etc/modprobe.conf.bak kudzu Thank you.
Hello, I have a dual AMD opteron processor 248 (speed 2.20 GHz) on a Tyan Thuder K8W (V2.04 BIOS) with 8 2GB DIMMS and I had the same problems: after the kernel 2.6.11 I lost 4 GB.

We saw something similar with a system here. 2.6.10-1.770_FC3smp uses uses the e820 info and 2.6.11-1.14_FC3smp uses the ACPI SRAT memory info. Boot with acpi=off and all the memory will be detected (but your system may be unstable so don't try to run that way). I think Dave Jones was correct to say that you have a BIOS bug.
a less drastic 'fix' may be to try numa=off
with numa=off or acpi=off it works, thankyou again.
does this mean a board problem? Kernel?
Just a BIOS problem, not a kernel problem. Download the newest BIOS from the Tyan website. http://www.tyan.com/support/html/bios_support.html If that doesn't fix the problem, email them with a link to this bug.
with numa=off I had a crash after two days from the boot.
