I'm having very similar simptoms after installing 10.04.1 from scratch
with two 500Gb disks (WD and ST).
The system installs and boots correctly if the raid1 array is created manually
from CLI before partitions detection.
But after some hours of uptime, errors start appearing in logs and the array
becomes degraded:

also in dmesg this message is present at every boot:
[ 3.022033] md1: p5 size 976269312 exceeds device capacity, limited
to end of disk
These are the partitions as seen from sfdisk:
~$ sudo sfdisk -l /dev/sda
Disk /dev/sda: 30401 cylinders, 255 heads, 63 sectors/track
Warning: The partition table looks like it was made
for C/H/S=*/81/63 (instead of 30401/255/63).
For this listing I'll assume that geometry.

DOS and Linux will interpret the contents differently.

This is /proc/mdstat output instead:

I'm at the third/fourth reinstall attempt (previously I've had the bad idea of
using raid1+luks+lvm now I've
switchet to plaintext) but I'm still having stability issues.
Can somebody confirm whether I'm hitting this bug?
