Hi!
As said in the title, my system hang completely unresponsive while transfer or extract files on my internal sata disk or on a usb key board.
Booting in intrepid is good as long as i don't copy oy extract a file...
Monitoring the system does not show a lot as memory or cpu uses they stay below 25 % ??
hdparm -tT gives me this result
/dev/sda:
Timing cached reads: 7046 MB in 2.00 seconds = 3526.36 MB/sec
Timing buffered disk reads: 248 MB in 3.03 seconds = 81.87 MB/sec

And the iv=

I changed as well the buffer size from 60 to 100 without any result.
if someone has a clue thank you.
