Hi,
 
I've seen the following URL http://jeffbastian.blogspot.com/2011/06/storage-speed-on-pandaboard-revisited.html and I've recognized the same problems.
If I connect over SSH to the Console the connection hangs continously. If I Ping the Board until I'm connected, then the connection is ok.
The same issue with a USB HDD, might be a problem with the USB connection?
 
Does anyone run into same issues?
 
Regards
Sven

Sven,

yes most likely it is. i've modified a pandaboard to remove the
LAN9514 and wire a host port connector to the EHCI. even with the
LAN9514 removed i am still have similar issues. this leaves the USB
PHY, the EHCI controller, and the EHCI driver. i'm working on
isolating the issue now.

Sven,

issue seems to have been resolved.

i've tested this change and verified the performance:

No, this fix is for a different issue. We are still seeing
performance issues on USB HD. The fix described fixes a different
race condition exposed with gcc-4.6 that kills all usb support on arm
(not just omap4).

See https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/709245
for more info. I added info to the bug report for people to reproduce
this on their systems.

I can confim this doesn't fix it, I've still the same problems as before.
I created a 500GB disk with ext3, it takes more than 20 Minutes.
