Hello It's the first time I try to report a kernel bug. If I'm reporting this at the wrong place or I'm doing something wrong, please point me the right direction. Thanks. I have a linkstation pro (from buffalo) which uses orion SOC. It runs debian wheezy with self compiled vanilla kernel. With "Marvell's Cryptographic Engine" (CONFIG_CRYPTO_DEV_MV_CESA) enabled, during boot, the following was in the kernel log: alg: hash: Test 6 failed for mv-hmac-sha1 00000000: 9a 5e 0d 81 ff f1 0b 69 3b 73 88 c8 d6 c9 13 d9 00000010: 06 e3 53 3e Without the hardware cryptographic support, everything seems normal. And on a Kirkwood machine (ls-wvl/E-AP from buffalo), the CESA engine works fine with the same version of kernel and the same cryptographic-related configurations. The CPU information: $ cat /proc/cpuinfo Processor : Feroceon rev 0 (v5l) BogoMIPS : 265.42 Features : swp half fastmult edsp CPU implementer : 0x41 CPU architecture: 5TEJ CPU variant : 0x0 CPU part : 0x926 CPU revision : 0 Hardware : Buffalo Linkstation Pro/Live Revision : 0000 Serial : 0000000000000000 The kernel config was attached. I tried various kernel versions, at least 2.6.38.8, 3.0.25 and 3.2.12~15. The results were all the same. (Am I supposed to attach the config as attachment or directly show the content here ?) regards cloudy
