[PROBLEM] Sata disk fail and Hang the machine

[Nicolo Chiellini]

Hi
i have a problem whit a machine, after some days of run i have a lot of this 
message on dmesg:

[...]
ata2: command 0x35 timeout, stat 0xd8 host_stat 0x0
ata2: status=0xd8 { Busy }
SCSI error : <1 0 0 0> return code = 0x8000002
sdb: Current: sense key=0xb
   ASC=0x47 ASCQ=0x0
end_request: I/O error, dev sdb, sector 338664038
Buffer I/O error on device sdb5, logical block 42332989
lost page write due to I/O error on sdb5
ATA: abnormal status 0xD8 on port 0xC88020C7
ATA: abnormal status 0xD8 on port 0xC88020C7
ATA: abnormal status 0xD8 on port 0xC88020C7
[..]

And i have also a lot of proces whit the flag D+ and Ds , impossible to 
kill:
root     25947  0.0  0.6  2364  792 pts/3    D+   12:31   0:00 /usr/bin/ls 
--color=auto -F -b -T 0 /mnt/sata

I cant list/write on the directory where the partition is mounted and i cant 
even reboot via software, realy bad for a remote server, :
root     24886  0.0  0.4  1544  584 ?        D    12:03   0:00 shutdown -r 0 
w

I need to know if that can be a hw problem or just a sw problem and how to 
fix, i'm installing the latest 2.6.13 whaiting the manual reboot.

Thanks, N.C.
