Yes, it should work and it's supported. But you may have trouble with a
root device, if it's initializing for a long time. I have seen this
situation with MegaRAID. In this case you system will not boot with
error: "switch to root: mount failed: No such file or directory".
You can workaround this problem by adding sleep in "init".
insmod /lib/dm-region-hash.ko
+sleep 10
mkblkdevs
It's not a kernel problem.
I don't recommend you use rhel6 kernel on rhel5 system for a long time.
You can install rhel6 kernel to try new features and to be sure that it
doesn't bring new problems, then I recommend update a host system too.
