end_request: I/O error, dev uba, sector 4000
Buffer I/O error on device uba, logical block 4000

when posting problems, please completely describe your system.
for example:
- what kernel/uclinux-dist version ?
- what toolchain version ?
- what is your board (platform) ?
- what USB controller are you using ?
- what USB devices (exactly) are you testing ?
- what are your relevant kernel settings (clock/bank timings/etc...) ?
- what commands exactly are you running and what exactly are the things you are seeing and what exactly were you instead expecting ?
