IO errors with 2.4.4 + System hangs a few seconds

[Rafael Martinez]

Hei

I have IO problems with a 2.4.4. kernel patched with linux-aic7xxx-6.1.13.

Trying to do a simple "cat file1 >> file2" a get in console this error:  
cat: file: Input/output error

And in /var/log/messages:

kernel: attempt to access beyond end of device
kernel: 08:11: rw=0, want=1887469700, limit=53785588
kernel: attempt to access beyond end of device
kernel: 08:11: rw=0, want=1887469700, limit=53785588
kernel: attempt to access beyond end of device
kernel: 08:11: rw=0, want=1887469700, limit=53785588

kernel: attempt to access beyond end of device

[ x lines, it can change from time to time, from 1 to 20 times]

This doesn't happen with all the files. With some files it happens with
others it doesn't.

Another problem is that the system hangs sometimes for a few seconds (from
2-3 up to 20sec) before giving me the control again . In this time I would
not get any respons from the system when I try to run a command, they just
hang, when the system comes back, I get all the results from the different
commands fast. I am not talking about heavy processes (w, free, ps ax, ls....) 

Any ideas? Do you need more info? 

Thanks for your time.
