Thanks. Please test using this image:
http://people.debian.org/~fjp/tmp/d-i/mini-megaraid.iso

It should now pause during hardware detection to wait for the megaraid 
reset to complete. It does not show any specific progress messages yet 
(except a few in the syslog), but I will add that if this works.

If it does not work, please uncomment the line '#set -x' near the top of
/bin/hw-detect and send the resulting syslog (or try fixing the problem 
yourself).

The one thing that could still be missing is that it does wait for 
megaraid reset to complete, but not for the detection of scsi devices 
that follows it, although I would expect that to work.
If that happens, try increasing the 'sleep 1' just before 'break' in the 
function wait_megaraid_complete in /bin/hw-detect to 'sleep 15'.

If it works, please also test with the following change. Again in the 
function wait_megaraid_complete change the line 'local wait=300' to
'local wait=10'. I'd expect the new delay to "time out" too early with 
that and thus show the old behavior.

The changes I mention above should of course be made before hw-detect gets 
run, e.g. while the language selection screen is being displayed.

Please send any syslogs from these tests (gzipped!).

I'd appreciate if you could do these tests within the next few days!

If you're using a regular CD image, then yes. That should not happen with 
the above image though.
