[Bug 455660] Re: MCP78S Chispet USB Ports Intermittent

[/dev/null]

Using Ubuntu 9.10 32-bit The issue is even worse...
Sometimes when writing data to an USB-Stick everything seems ok. Ubuntu tells no errors, but  after running md5sum on both source and destination you will see the files are NOT identical.
Sometimes the data transfer just stops as if the copy was ok but only a small amount of the file was copied.

I have been aware of this after copying a divx video to my stick and
wanted to play it on a standalone player which said: unknown format... I
was curious about this... but the stick back in well mplayer was able to
play but without the possibility of searching within the file...

btw. When enabling the 3D-Desktop or watching a video it is much worse
than without.

I am using the proprietary driver : NVIDIA-Linux-x86-190.53

My System is: ASRock K10N78FullHD-hSLI
CPU: AMD Phenom(tm) 8650 Triple-Core Processor
