This might be a firmware issue, I am in the process of trying to get firmware updated on this for BZ 463144 also.
It appears the firmware update did not resolve this. I tried booting vmlinuz-2.6.18-92.el5debug and hit the same lockup issue.
-124debug boots, but now the lockdep hits a bug on infinite recursion. I'll attach the dmesg here.
Created attachment 324740 [details] dmesg output with the lockdep bug
Hi Aristeu, do you have any update?
No, I'll check if the problem still exists
