September 11, 20196 yr Thanks for the video. Please run similar test again, this time right after the timeout writing copying large file, please capture diagnostics and post here.
December 21, 20205 yr This issue caused me some headache as well... Turns out the Intel C3000 Atom platform has support for something called Intel QuickAssist Technology (Intel QAT, https://www.intel.com/content/www/us/en/architecture-and-technology/intel-quick-assist-technology-overview.html). The kernel driver for this feature is what is causing the issue with LUKS/dm-crypt. The QAT kernel driver takes precedence when both AES-NI and QAT is activated so the solution is to either blacklist the kernel module or disabling the QAT feature in BIOS. I have a Super Micro board and the setting for QAT was found under the south bridge configuration (IQAT). As a bonus the performance with AES-NI compared to QAT was twice as fast (according to cryptsetup benchmark)

I had given up on using encryption with unraid but I will look into turning of QAT through BIOS and try it again. bubiman
