Hi,

I'm experiencing problems with my Promise SATAII TX4 controller, quite
similar to what Kim reported a few months ago.

Using a fresh linux-2.6.12.5 upstream kernel to boot into a rescue shell
(so there's no distribution specific stuff going on, nothing else
loaded, etc.), I can access my three connected Maxtor 120GB drives just
fine, as long as I do so individually.

OK, apparently it's somewhat hardware related after all. I've added a
Seagate drive (Model: ST3120827AS, Rev: 3.42) and reading from this
drive together with two of the Maxtor drives (any two of the three)
currently works without problems (for now).

Switching ports and cables doesn't change anything, so it's not related
to that.

But how can that be? The individual drives don't reveal any problems and
(as reported in my previous mail) the drives worked seamlessly for a few
weeks ...

I'll have to do some more testing and this is probably off-topic by now,
so I'll stop with the noise now.
