[linux-lvm] Kernel crash (2.4.27 + DeviceMapper + grsecurity)

I am wondering if some people are running a 2.4.27 kernel with both
device-mapper and grsecurity.
I've been using these patches with the 2.4.25 and 2.4.26 kernel without
Since I have upgraded to 2.4.27, I have experienced two system crashes.
I have no oops, but using a serial cable and Magic sys keys, I can see
that these two crashes happened at 06:25 during logs rotation:
savelog S 00000000 3948 18480 24071 22315 (NOTLB)
mv R current 8 22315 18480 (NOTLB)
Each time the last process is "mv" (stuck in a system call).
The EIP seems to show that the system is stuck in gr_handle_rename
(which is in gracl.c).
(I don't know if it is relevant, but as it was the same for both crashes
I guess there is perhaps something weird here...).
The DM patch I'm using is linux-2.4.26-rc1-devmapper-ioctl.patch.gz.
P.-S.: please CC me as I'm not on this list...
