FYI, I too have experienced this. My configuration is similar to yours:
2.1.129 (UP)
Adaptec 2940UW
ID 0 - Iomega ZIP 100
ID 1 - UMAX Astra 610S
AMD K6-300/128MB RAM, 2 IDE HDs

I experienced the problem with SANE 1.0. I was previously using SANE
(I do not recall the version) under 2.1.126 without problems.
I don't get any log messages whatsoever, and I haven't experienced any
system lockups, but the scanner just sits there with its light on and
the scan head about halfway down the deck until I power cycle it (resetting
the computer does not reset the scanner).
Is there a configuration option for the aic7xxx driver that we can turn
on to enable debugging information, or any specific tests that we could
run to see what's going on?
