I use a Adaptec 2740 Adapter. In RedHat Linux 5.1 the SCSI Adapter was detected well and I can so use my SCSI CDROM to Install Linux. In 5.2, the driver Adapter 2740,2840,2940 SCSI cause an error and the installer stops. Error Message : "Kernel Panic aic7xxx : unrecoverable BRKADRINT"
We will need to obtain one of these particular cards in our test lab to accurately try to reproduce this bug.
Are you still experiencing problems with this card? Were you able to install 6.0 on the machine? Reopen this bug if you are still seeing problems with this particular Adaptec card.
