This bug looks to be fixed in the d-i serial 20101020ubuntu540 build.
Should we close this bug?

As suggested by Brian, I was finally able to use scsi_mod.scan=sync kerenl
parameter and the problem is not reproducible, although the hardware detection
phase is a bit slower.
The problem is that ipr is taking more than a minut
