Hi guys, |
| 2 |
|
| 3 |
I'm encountering a reproduceable problem with hardened 2.6.26-r9 and |
| 4 |
2.6.27-r8 that wasn't there with 2.6.25-r13 on i686, and isn't there |
| 5 |
with amd64 using approximately the same kernel configuration in every |
| 6 |
case. I've been able to reproduce it in vmware, qemu and on physical |
| 7 |
boxes, one with a Intel(R) Core(TM)2 Quad CPU Q6700, the other AMD |
| 8 |
Athlon(tm) 64 FX-62 Dual Core. It a stack fault in kernel mode, but I |
| 9 |
can't pin it down further. It happens almost immediately after the |
| 10 |
bootloader passes control to the kernel. The best error message comes |
| 11 |
from qemu which gives the states of the registers. Here's the error |
| 12 |
message from a bootable ISO I made suing 2.6.26-r9. Any idea where I |
| 13 |
can start tackling this one? |
