Well, I'm puzzled. On the one hand, your oopses don't all look the
same, so we could think it's a hardware problem. On the other hand,
your hardware tests did not find anything and 2.6.14 runs fine. BTW,
I also have other machines running in production with an adaptec
29160 like yours and I don't encounter this. It looks like some
memory corruption, but finding what causes it seems very hard. In
fact, it somewhat reminds me the problems encountered by Stephan
von Krawczynski 2.5 years ago. He encountered data corruption when
saving large amounts of data to a DLT connected to an AIC7xxx, and
often had freezes, and sometimes an oops. IIRC, changing the board
for something else fixed his problem.
I've compared the driver between 2.4 and 2.6, and the core has not
changed much, but its interface to the OS has changed a lot, so it's
not easy to identify a potential fix.
Eventhough I don't like this, I would join Roberto's advice to
upgrade to 2.6 and stick to it. If you finally encounter the
same problem on 2.6 after a very long time, then it would be
an indication that the problem is well in your hardware.

Thanks for all your investigations,
