* [gentoo-dev] Need an x86 tester with >=1GB RAM (and some time to spare)

Hi,

Theres a bug filed against gentoo-sources-2.6 which causes the system to be 
unreliable when running the 64GB highmem option. This bug isn't present in the 
vanilla kernels so it must be caused by one of the patches we apply, but I 
don't know which this might be.

To see this bug, you need to have _some_ highmem in the system (this means >= 
1GB total physical RAM), be running on x86 (other arches dont have HIGHMEM 
option), and have the 64GB high memory support option enabled. (4gb is fine, 
as is lowmem)

I've had this bug reproduced by a few different people, but none of them with 
enough time to help me diagnose this. I only have 512mb myself so I can't help.

If anyone has the appropriate hardware and some time to spare slowly reverting 
out the Gentoo patches to help diagnose the problem, please take a look at 
http://bugs.gentoo.org/show_bug.cgi?id=101359

Thanks!
Daniel

I currently have 1GB of RAM with the 4GB HIMEM on 2.6.12-gentoo-r9.  I 
can play with it.

Sounds like it's time to upgrade ;-)

I can definitely do that on one of my days off work (Mondays and 
Tuesdays).  Shouldn't be terribly difficult with the newer, smaller 
patchset.

Ok...

Linux oneill 2.6.13-gentoo-hugemem #3 Fri Sep 2 11:41:01 PDT 2005 i686 
AMD Athlon(tm) XP 2800+ AuthenticAMD GNU/Linux

Linux version 2.6.13-gentoo-hugemem (root@oneill) (gcc version 
3.3.5-20050130 (Gentoo 3.3.5.20050130-r1, ssp-3.3.5.20050130-1, 
pie-8.7.7.1)) #3 Fri Sep 2 11:41:01 PDT 2005

This is with:
# CONFIG_NOHIGHMEM is not set
# CONFIG_HIGHMEM4G is not set
CONFIG_HIGHMEM64G=y
CONFIG_HIGHMEM=y
CONFIG_X86_PAE=y
CONFIG_SELECT_MEMORY_MODEL=y
CONFIG_FLATMEM_MANUAL=y
# CONFIG_DISCONTIGMEM_MANUAL is not set
# CONFIG_SPARSEMEM_MANUAL is not set
CONFIG_FLATMEM=y
CONFIG_FLAT_NODE_MEM_MAP=y

System boots just fine.  The only thing I didn't do was use genkernel. 
Guess I'll give that a whirl, see if my results differ.
