Hi folks,
I’m having boot problems as of lately and can’ t seem to find a way to diagnose what is wrong. Can somebody help me out?
Usually I can boot with no problems but sometimes I have to hit CTRL-D or type some other command to start.
A dmesg | grep md gives:
9.998728] boot.md[460]: Starting MD RAID mdadm: /dev/md2 is already in use.

What I find strange above is:
