[grsec] PAX enabled kernel and suspend2 - hangs during hibernate-ram

[Lubomir Host]

Hi,

I'm trying to enable PAX in kernel 2.6.19.2 patched with suspend2 patch.
Script hibernate-ram works great on my laptop, if PAX is not enabled
(works on my 2.6.19.1-grsec kernel with the same suspend2 patch).

After enabling PAX options hibernate-ram scripts hangs with
following error:

Stopping tasks ... done.
Suspending console(s)

and laptop doesn't get hibernated. I can oonly turn off laptop with
power button.

PAX kernel config:

CONFIG_PAX_NOEXEC=y
CONFIG_PAX_SEGMEXEC=y
CONFIG_PAX_MPROTECT=y
CONFIG_PAX_NOELFRELOCS=y
CONFIG_PAX_KERNEXEC=y

CONFIG_PAX_ASLR=y
CONFIG_PAX_RANDKSTACK=y
CONFIG_PAX_RANDUSTACK=y
CONFIG_PAX_RANDMMAP=y

CONFIG_PAX_MEMORY_SANITIZE=y
CONFIG_PAX_MEMORY_UDEREF=y

Any ideas? Can I turn off some PAX options without security affect?

Thanks, best regards
