thanks, i fixed it. in the meantime you can disable CONFIG_X86_RESERVE_LOW_64K to get it to boot.

root@testing:/boot# grep CONFIG_X86_RESERVE_LOW_64K config-2.6.33
# CONFIG_X86_RESERVE_LOW_64K is not set
root@testing:/boot#
didnt helped

still "booting the kernel" and nothing more

can you try the latest PaX test patch? if that still fails, i'll need your bzImage/vmlinux.

you'll need to fix your .config when moving from grsec to PaX, it's been discussed many times on the forum ;P.
