Hi Jack, I'm sorry to bother you during holidays. I encountered a strange problem installing AlmaLinux 9.1 on a RAID1 (MDADM) with the current configuration: - /boot/efi on md125 - swap on md126 - / on md127 disks are 2 SSD MLC Type. After the installation, if I reboot the system I get: "md: md125 stopped" (it is printed many times like in a loop) alternated with: "systemd-shutdown[1]: Not all MD devices stopped, 1 left Stopping MD Devices Stopping MD /dev/md125 (9:125)" and the system hangs on this loop until I cut the power. I encountered this issue on my Workstation with Asus Prime Z490-A / i9-10850k. I tried with another workstation that runs on Asus Prime Z370-A / i7 8700K, to exclude bad SATA controller and bad cables. Also on the second workstation the problem is found. I tried to replicate this using 9.0 ISO. The problem does not occur until I update to 9.1 I tried also with 8.7. No problem here. I tried also RockyLinux 9.1 and got the same problem but with different messages: "block device autoconfig is deprecated and will removed" alternated with: "blkdev_get_no_open: 270 callbacks suppressed." To stop the machine I need to cut the power. I tried also Debian 11.5 without problems. So seems that the problem is 9.1 related. Actually I can't test the same with RHEL 9.1 but probably the problem will occour also on RHEL 9.1 There is a way to fix this or I should wait an upgrade? Thank you in advance.
