Gentoo hardened -- kernel panic on boot


I have been (repeatedly) setting up a laptop (HP Pavilion dv4000 attached to a docking station) for use as a home server (using Gentoo.)

After trying two installations, one hardened (which succeeded, but I messed up later (disabled the root account with "passwd -l", and PAM didn't like it) and one not hardened (which worked fine,) I am now trying a new hardened installation.

Apart from file system support and possibly turning off "prompt for incomplete/experimental drivers," I have a fully default hardened Gentoo kernel on it. However, I am getting the following panic (stacktrace omitted):

Code:
[    15.6930006] Code: 00 00 00 03 04 95 80 a0 ef c1 ff 80 14 a0 02 c1 5d c3 55 89 e5 57 56 53 83 ec 48 83 7d 08 00 89 45 b8 89 55 b4 66 89 4d b2 75 04 <0f> 0b eb fe 64 8b 15 84 00 00 00 b8 28 44 00 00 0f b7 4d b2 03
[    15.693006] EIP: [<c19103c8] avc_has_perm_noaudit+0x19/0x366 SS:ESP 0068:f6555c40
[    15.701663] KXernel panic - not syncing: Fatal exception in interrupt
I'm wondering what's going on here, since a hardened installation performed a few weeks ago worked fine (the aforementioned first hardened installation.)

Thank you for any help.

EDIT:
Well, it appears that kernel version 2.6.28-r9 from hardened-sources does not work correctly here. 2.6.28-r7 (the next newest version) works fine.
I will be filing a bug (for Gentoo.)
EDIT2:
Well, after narrowing down the version, I found that this bug was already filed (I would not have found it before.)
