I can confirm this but only for smp-kernel, with up-kernel it works.
Not for me. Get segmantation faults with both kernel-2.6.10-1.766_FC3 and kernel-smp-2.6.10-1.766_FC3
I confirm I get this too with 2.6.10-1.766_FC3 UP.
After investigations, I found that this bug has been reported upstream and is caused by grub using dynamically allocated pages to put executable code which causes problems because of x86_64 NX feature. A patch which converts malloc to mmap for this memory is provided in the upstream bug report at: http://savannah.gnu.org/bugs/?func=detailitem&item_id=11312 I tested this patch and can confirm that it does fix grub's segfaults for me. Stelian.
Tried grub-0.95-11.x86_64 from rawide. First tried to apply tie patch to SRPM and rebuild. Does not have exactly the patch above but does have an overlapping one that seems to do the trick. The rawhide binary RPM works. Changing to RESOLVED/RAWHIDE.
