Public bug reported:
I have two PATA hard disks connected to an IT/ITE8212 Dual channel ATA
RAID controller as the kernel messages below indicate:

The problem is that while the messages here indicate that the existing
partitions on these disks are seen, no equivalent device node file is
created under /dev for /dev/sda1 /dev/sda2 /dev/sdb1 and /dev/sdb2. Only
/dev/sda and /dev/sdb are made. Yet fdisk -l will list the partitions:
fdisk -l
Disk /dev/sda: 203.9 GB, 203928109056 bytes
255 heads, 63 sectors/track, 24792 cylinders

--snip fdisk output--
Manually creating the /dev/sdaX and /dev/sdbX with mknod does not help:
mdadm -Q /dev/sda1
mdadm: cannot open /dev/sda1: No such device or address
mdadm -Q /dev/sdb1
mdadm: cannot open /dev/sdb1: No such device or address
Interesting output from lshw where it says that both partitions are
