Hi.

Just run into this bug using 12.04 Ubuntu and 3.2.0-24-generic kernel.

here is the syslog:

May  6 00:57:02 Vouhaukko2 CRON[10944]: (root) CMD (if [ -x 
/usr/share/mdadm/checkarray ] && [ $(date +%d) -le 7 ]; then 
/usr/share/mdadm/checkarray --cron --all --idle --quiet; fi)
May  6 00:57:02 Vouhaukko2 kernel: [738906.402166] md: data-check of RAID array 
md0
May  6 00:57:02 Vouhaukko2 kernel: [738906.402173] md: minimum _guaranteed_  
speed: 1000 KB/sec/disk.
May  6 00:57:02 Vouhaukko2 kernel: [738906.402179] md: using maximum available 
idle IO bandwidth (but not more than 200000 KB/sec) for data-check.
May  6 00:57:02 Vouhaukko2 kernel: [738906.402187] md: using 128k window, over 
a total of 488384448k.
May  6 00:57:02 Vouhaukko2 mdadm[1216]: RebuildStarted event detected on md 
device /dev/md0

and after that it hangs.

Anything I can do to help nail it?
