Not sure since there aren't any errors logged and you're the only one having this issue, maybe try v6.8 that will be released soon, newer kernel might make a difference. Quote Link to comment

inf Posted December 21, 2020 Share Posted December 21, 2020 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) Quote Link to comment

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