I just tried this with kernel-xen-2.6.18-1.2784.fc6 xen-3.0.2-44 qemu-0.8.2-3.fc6 And it worked for me. Could you verify that the latest kernel-xen fixes this problem? Created attachment 138700 [details]
core.gz of: qemu -cdrom /dev/zero -net none -m 1
kernel-xen-2.6.18-1.2798.fc6.i686
xen-3.0.2-45.el5.i386
qemu-0.8.2-3.fc6.i386
It is sad you could not reproduce it. Really running i386 (32-bit)?
It is workaroundable by echo 0 >/proc/sys/kernel/exec-shield (still on that kernel-xen-2.6.18-1.2798.fc6.i686) as suggested by Caolan McNamara in Bug 210748. Still not aware of the specific cause but I assume you already know. No I didn't notice that this was for i386 only. You did mention that you were using that, but I wasn't. So I was able to get it to seg fault. OK, now that I have something that doesn't work, I can take a closer look at it. I also switched this BZ to state that this is not for all hardware, but for i686. The fix for bz 200382 seems to have caused this bug. Will look into it further. OK, I've confirmed that the fix for 200382 caused this problem. I have a patch that has already been submitted to the maintainers. But I must first confirm that the patch doesn't break 200382 before I close this. change QA contact Tried with 2.6.20-1.2933.fc6xen.i686, with execshield enabled; seems to work fine. Since this seems to work on FC6 and RHEL-5, closing this bug out. Please re-open if you still have problems. Chris Lalancette |
