Hello, running Fedora 27 on an Intel Atom C3758 CPU Supermicro system (A2SDi-8C+-HLN4F) I've noticed that crypto selftests fail when the qat_c3xxx module is loaded (it is loaded, by default). That means that stuff like `modprobe dm-crypt`, `cryptsetup benchmark` and `cryptsetup luksOpen` fail. The kernel log then contains the following messages: alg: akcipher: encrypt test failed. err -22 alg: akcipher: test 1 failed for pkcs1pad(qat-rsa,sha256), err=-22 When I blacklist the qat_c3xxx/intel_qat modules the crypto works as expected. I can reproduce this issue with 4.14.3-300.fc27.x86_64, kernel-4.13.16-302.fc27.x86_64 and kernel-4.13.9-300.fc27.x86-64. See also my report in the Fedora bug tracker: https://bugzilla.redhat.com/show_bug.cgi?id=1522962#c5 The loaded firmware has this checksum: md5sum /lib/firmware/qat_c3xxx_mmp.bin fb7deea913d87aed7676222269a593e6 /lib/firmware/qat_c3xxx_mmp.bin Is this an issue with the driver, the firmware or does the QAT co-processor need some additional setup?
