Ugh... that sounds like the RAID controller is hanging/resetting very badly
or the driver is behaving weirdly :-(
It can be then a bug in the megasas kernel module and Google finds *lots*
of similar errors for that same driver, and curiously, xen kernels:
http://www.google.com/webhp?complete=0&hl=en#hl=en&tbo=1&complete=0&site=webhp&tbs=qdr:y&q=LSI+megasas:+RESET+-4637+cmd%3D2a+retries%3D0&tbo=1&bav=on.2,or.r_gc.r_pw.,cf.osb&fp=e8f1b276e45aa3ef&biw=1280&bih=888
I wouldn't discard this is still happening on wheezy... although the
installer can succeed, what will happen once the system enters into
high load? Will the driver experience the same problems?
Are you using the NET ISO image to install Debian? If no, I would do a
final try using it, just to discard bad media and/or DVD read errors.
