>Organization:
UT AUstin
>Environment:
FreeBSD ozzy.hauschen 4.3-CURRENT FreeBSD 4.3-CURRENT #2 Wed Jun 13 10:54:49 GMT 2001   busterb@ozzy.hauschen:/usr/src/sys/compile/OZZY  i386 - note, this is from the last time I could get uname -a to work (since the kernel hangs).
>Description:
Updating a Compaq Prosignia VS (EISA) from FreeBSD 4.3-CURRENT to 4.4-PRERELEASE causes kernel to hang on boot right before it normally prints "Waiting for SCSI devices to settle". No error messages, just a hang. Using an EISA Adaptec 2740A card.
>How-To-Repeat:
Boot EISA machine using Adaptec 2740A card with 4.4-RELEASE. Note, I have only tried this with the Compaq, which has worked since FreeBSD 2.8.
>Fix:
Tried to get older versions of aic7xxx driver from CVS to see if recent merges from HEAD were the culprit. Couldn't get the mess to compile (the rest of the kernel was still 4.4 PRERELEASE.)
