>Description:
When the ata1-master disk come back from sleep (configured by ataidle), it is removed and I can't browse it anymore. A manual umount makes the server rebooting.

Here are the logs for the event:
kernel: ad2: TIMEOUT - READ_DMA retrying (2 retries left) LBA=265761311
kernel: ad2: WARNING - removed from configuration
kernel: ata1-master: FAILURE - READ_DMA timed out
kernel: ata1-master: timeout state=0 unexpected

It is a new 200Go Maxtor disk:
ad2: 194481MB <Maxtor 6B200P0/BAH41BY0> [395136/16/63] at ata1-master UDMA133

Config ataidle:
/usr/local/sbin/ataidle -S 20 1 0 (in rc.local)
