Just updated, and kernel 2.6.26-0.85.rc7.git1.fc10.x86_64 results in: PANIC: early exception 06 rip 10:ffffffff8114a546 error 0 cr2 0 2.6.26-0.72.rc6.git2.fc10.x86_64 boots normally. This is a Dell Optiplex 755. I'll try a new mkinitrd, as the panic is immediately after the boot info is displayed. jerry
