Using 2.6.16-rc5-git4 and removing a directory of around 5.0GB of files 
while streaming a 1MB/s video stream on another (SATA disk), the I/O 
seemed to freeze up for a moment and I got this error:

[4342671.839000] ata1: command 0x35 timeout, stat 0x50 host_stat 0x22

Only 1 in dmesg, any idea what causes this error?
