The card is correctly recognized and the aha152x driver is loaded. The CD-ROM drive (tried with 2) attached is not recognized, and the driver goes into a slow polling loop to look for devices it can't see. This happens for the RH 6.0 install (I needed to workaround this w/an NFS installation), and in the complete installed RH 6.0 system as well. Built a 2.2.12 kernel and now everything works, leading me to believe the 2.2.5-15 default build is the culprit. This was an Epson ActionNote 910C (w/Cyrix 586).
