(Found out not to put aic7xxx in subject line because of spam filter...)
Running with latest 2.6.11 bk tree, one of my machines takes for ever to boot.
The driver is builtin (not a module). It worked fine until today, and works
fine with 2.6.11 or earlier. Looks like it is going into some probing fallback
unwind code mess... This is the current driver not the old driver.
The scsi controller is:

During boot up the console output is...
