i encountered the same problem with that patch.

I did not.

Maybe you did because you did not select any PAX Options?

I've the same problem here. And I didn't select any options from PAX.
Anything that should have been chosen on PAX?

should be fixed in the latest PaX test patch.

where can i find that one? is that grsecurity-2.1.9-2.6.17.6-200607241736.patch at spender?

Thanks for that.

Initiate attempts with the new patch produce the same results. However enabling PAX softmode and etc seems to have solved the problem. Here's part of my .config setting:

CONFIG_PAX=y
CONFIG_PAX_SOFTMODE=y
CONFIG_PAX_EI_PAX=y
CONFIG_PAX_PT_PAX_FLAGS=y
# CONFIG_PAX_NO_ACL_FLAGS is not set
CONFIG_PAX_HAVE_ACL_FLAGS=y
# CONFIG_PAX_HOOK_ACL_FLAGS is not set
CONFIG_PAX_NOEXEC=y
CONFIG_PAX_PAGEEXEC=y
CONFIG_PAX_SEGMEXEC=y
# CONFIG_PAX_DEFAULT_PAGEEXEC is not set
CONFIG_PAX_DEFAULT_SEGMEXEC=y
# CONFIG_PAX_EMUTRAMP is not set
CONFIG_PAX_MPROTECT=y
# CONFIG_PAX_NOELFRELOCS is not set
CONFIG_PAX_KERNEXEC=y
CONFIG_PAX_ASLR=y
# CONFIG_PAX_RANDKSTACK is not set
CONFIG_PAX_RANDUSTACK=y
CONFIG_PAX_RANDMMAP=y
CONFIG_PAX_NOVSYSCALL=y
CONFIG_PAX_MEMORY_SANITIZE=y
CONFIG_PAX_MEMORY_UDEREF=y

Thanks again.
