[Bug 79542] Adaptec 39320D slows down boot

[karaluh]

Public bug reported:

Dapper, 2.6.15-27-386. System freezes for 41 seconds on "Mounting root filesystem". I've found, that it's happening because of Adaptec's 39320D SCSI card. If it's pluged out, system boots normaly. Google, forum.ubuntu.pl and ubuntuforums.org weren't helpful. I used dmesg and peace of paper and got this:
