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 ?
