Hello, |
2 |
|
3 |
I've got some kind of strange situation which took me a few days to find |
4 |
out. It all started with a pentium 4 machine on an ASUS P5AD2 board that |
5 |
would just refuse to boot a hardened kernel after being freshly set up |
6 |
with a 2005.1 hardened profile. |
7 |
|
8 |
GRUB came find and then if I selected a hardened kernel |
9 |
(2.6.11-hardened-r15 or 2.6.13-hardened-r2) I could barely see the |
10 |
"booting linux" and then the machine rebooted as if someone had pushed |
11 |
the reset button. Standard gentoo kernel booted just fine. The rest of |
12 |
the installation was stable and the machine ran under full load for a |
13 |
few days. |
14 |
|
15 |
There was no way to boot a hardened kernel except disabling the "Disable |
16 |
execute function" is the BIOS. |
17 |
|
18 |
I finally tracked down the problem to selecting 64GB under High Memory |
19 |
Support in the kernel. If I select 4GB the hardened kernel boots, with |
20 |
64GB it doesn't. The machine itself has 2 GB of RAM. Standard gentoo |
21 |
kernel boot regardlessly whether I select 4 or 64GB. I even disabled |
22 |
everything under "Security options" in the hardened kernel, but that |
23 |
didn't help either. |
24 |
|
25 |
|
26 |
I can boot the machine with: |
27 |
- gentoo-sources 2.6.13-gentoo-r5 and High memory = 4GB OR 64GB |
28 |
- 2.6.13-hardened-r2 and High memory = 4GB |
29 |
- 2.6.13-hardened-r2 and High memory = 64GB and Disable Execute option |
30 |
OFF in the BIOS |
31 |
|
32 |
|
33 |
So basically my question is whether this is the intented behaviour or |
34 |
not? |
35 |
