sata hard drive: Seagate 200 Go 7200 RPM 8 Mo Serial ATA


Software Environment:

when I use cp command on the sata hard drive with large data or access for read.

Problem Description:

copy or access is stopped :

Aug 11 19:13:25 localhost kernel: [17202123.796000] ata1: command 0x25 timeout,
stat 0x58 host_stat 0x62

Steps to reproduce:

copy large data from the disk. There is no issue with 2.6.12.4 kernel. However,
with other 2.6 kernels, copy are slow (speed of 20 MByte/s for read)
