Ubuntu Server on DL20Gen10 with P408i-a(RAID1): slow boot
I installed Ubuntu 20.04 on my DL20 Gen10. All seems to work, but booting takes a long time. The following spot in dmseg seems to be the culprit (going from 3.662367 to 123.389845)
Not sure why here it mentions RAID6, because the installed P408i-a is setup as RAID1. It seems that two scsi devices are involved. What is it doing for 2 minutes? Also on the console there is an extra message (not logged in dmseg) generated during these 2 minutes:
Begin: Loading essential drivers … [. 123.389845] raid6: avx2x4. Gen(). 31519 MB/s
So how can I get Ubuntu kernel to do the right thing here? (related: what is difference between 6:1:0:0:and 6:2:0:0:? Wrong setup? Do I need to disable (hard- or software) something?)
Thanks!
Relevant part of dmseg:

EDIT: I have come to realize that Ubuntu 20.04LTS is incompatible with DL20gen10, probably due to the hardware raid (P408i-a). Now installed RHEL8.5 and total dmseg is 10 seconds
