Red Hat Bugzilla – Bug 174655
memory problems with > 2G
Last modified: 2015-01-04 17:23:22 EST
Description of problem:
kernel-2.6.14-1.1632_FC5 only see 2.8G when 4G is installed.
Later kernels, including kernel-2.6.14-1.1719_FC5, go into some very early panic
when > 2G installed.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install 4G memory
4G real memory should work on a 64bit processor
can you grab the latest kernel from
http://people.redhat.com/davej/kernels/Fedora/devel/ and paste the output of
dmesg -s 128000 please ?
(The panic should be fixed in 1725 and newer)
(I hate the way bugs in NEEDINFO state disappear from "My Bugs" in Bugzilla!)
I'm not close to the machine now, but when retried with 4G yesterday, with 1739
I think, I was still getting panics very early in the reboot sequence.
No opportunity to run dmesg.
I tried with and without the bios option of filling the memory hole.

This also with mkinitrd-5.0.10-1 since sofware rid doesn't work with

I see this too. Still happens with 1740 from people.redhat.com. ASUS SK8N
motherboard, AMIBIOS revision 1004.
This doesn't seem to happen any more.
