[Bug 229747] Re: "port is slow to respond" error freezes OS for seconds while reading HDs

[neferty]

I confirm this problem persists on Lucid Lynx Netbook Remix. Using
Samsung N130 the system randomly freezes for about 15-25 seconds
(sometimes the interface; sometimes even the mouse doesn't move). I get
the following dmesg:
