[Bug 297058] Re: Consistent repeating [ata1: link is slow to respond, please be patient ]

[Ralph]

Reconfirmed with 10.04 (Dell Inspiron 2200), kernel 2.6.32-24-generic.

The behavior is a system-freeze (I/O wait, actually) until the reset,
after which all is OK.  SMART indicates a healthy drive (I get this with
multiple drives) and passes all self-tests.

As this is a laptop I'm limited in terms of replacing cables or changing
drive-select options.  I still feel this is a kernel/driver issue, and
would welcome input from someone familiar with what's going on at this
level.
