Yes, i did from the early 2.1.x times on.
The question is which Linux version you are using _and_
which aic7xxx version if any.

It turned out to be a mass i/o lock which can be seen without LVM too.
Things turned out to be better in the later 2.1.x and in 2.2.x.

A problem still stays which Stephen Tweedie and others are addressing right now:
with large quantity i/o 2.2.1 preferes allocation of buffer pages vs.
keeping process pages in memory making the system _very_ lazy ;*)
