Hi,
I'm having a bit of a problem with some SATA drives in docking stations connected to USB ports.
The problem seems to be unrelated to heavy I/O and occurs randomly. Once, without the drive even being mounted.
Here's a sample of output from /var/log/messages:

I also have made a couple of bug reports which appear to be getting no attention.
[Bug 802607] New: reset high-speed USB device (sata drive and USB connection)
I've started loosing data now.
Does anyone have any clues?
The system is running FC 16 x86_64 fully up to date. The problem has persisted across several kernels including the current kernel.
Any help would be greatly appreciated.
Thanks,
George...
