Hi Everyone,

I got a question regarding boot entries I noticed.
During the part "loading essential drivers" I noticed a couple of entries like this:
<system> kernel: raid6: avx2x4 gen() 49362 MB/s
<system> kernel: raid6: avx2x4 xor() 22862 MB/s
<system> kernel: raid6: avx2x2 gen() 50122 MB/s
...

Is it possible I'm having a HW-Raid that I'm not aware of (MB Fujitsu/Kontron D-3644-B1)?
Although I have definetely not configured anything like it.
SATA Mode is AHCI in Bios.
I tried to google it, but haven't found anything so far, so sorry if it's a stupid question :D

No, clearly not. There appears to be a Linux driver to do RAID6 and it appears to be testing the speed of your CPU's underlying bitwise operations to do the RAID math. In any case, it doesn't matter since TrueNAS doesn't support RAID6. It's just random garbage that comes along with basing the OS on a generic upstream like Debian.

I couldn't imagine, but thanks for confirmation!
