I'll repeat what I said in the bug report here
(See https://bugs.gentoo.org/show_bug.cgi?id=349705)

hardened-sources-2.6.32-r31 has grsecurity-2.2.1-2.6.32.27-201012121726

hardened-sources-2.6.36-r6 has grsecurity-2.2.1-2.6.36.2-201012121726


What's even stranger is that I have six HP Proliant DL 385 G7, all with
the following (partial) fstab:

/dev/cciss/c0d0p1 /boot ext2 noauto,noatime 1 2
/dev/cciss/c0d0p3 / ext4 noatime 0 1
/dev/cciss/c0d0p2 none swap sw 0 0

None of which showed a panic.
