This is swap, I do not recall seeing this error in kernels < 2.6.28, should
the kernel not scan for partitions on a swap-based parititon? [1]
this is probably due to the fact that now /dev/md* are partitionable.
[2] partitions for mdadm/raid are usually md0_p1 md1_p2 why would it scan for
partitions on /dev/md0, /dev/md1, /dev/md2 as they are 'block devices' e.g.,
similar to /dev/sda, /dev/sdb, /dev/sdc
I do have the option checked off:
[*] Autodetect RAID arrays during kernel boot
As I compile everything in statically, no modules are used.
If I disable that option, would my system still boot/that would get rid of
the error/so it does not try to scan for partitions on swap?
no
if you want to get rid of that you can disable kernel partition
detection, but you have to do it manually in initrd/init scripts/udev
rules then(*)
(*) i still firmly believe that partition detection does not belong to
the kernel any more than raid/lvm.
