Re: 2.4.3 2.4.4pre8: aic7xxx showstopper bug fails to detect sda

[poptix]

Howdy,

	I've got an "Adaptec AHA-2940UW Pro Ultra SCSI host adapter" using
the aic7xxx driver (the new one, not the old one), and have had no
problems, I have a zip drive on ID5, and a 12X Smart & Friendly CD-RW on
ID6, haven't had any problems on 2.4.3-ac14, or 2.4.4, just an FYI.
