Looking around a bit it seems that the error reported is a timeout error.  A very similar bug was filed under number 514155 for the 508x/6081 8-port controller chips.

Hi,
The next release of Debian (6.0, code name Squeeze) will be based
on 2.6.32. Please test the current 2.6.32 from unstable/testing and tell
us whether the problem persists. If so, we should report it upstream
to the kernel.org developers.

The 2.6.32 kernel is available from packages.debian.org and can
be installed in both Debian stable, testing and unstable
installations.

Thanks,
