I'm having this issue since I update the IOS from 12.4(9)T to 12.4(24)T2. So I tried 12.4(22)T, 12.4(20)T, 12.4(15)T. With every version the problem is always the same (reboots continuosly).Then I had back to 12.4(9)T and the router starts up normally but show me this line (always do):
*Dec 28 21:33:44.395: %CRYPTO-0-SELF_TEST_FAILURE: Encryption self-test failed (DH test)
And cannot create a crypto key for ssh (for example).
The router has no config.
In the attach you can see "sh ver", "sh inventory" and a full boot cycle from one "Self decompressing the image" to the other.
Will appreciate any help.
