Building the driver for pcmcia aha152x cards is disabled for 64 Bit kernels. Searching for the reason for this I did not find anything. Then I built the driver removing the "depends on !64BIT" line in the config PCMCIA_AHA152X section in /usr/src/linux/drivers/scsi/pcmcia/Kconfig. Full information on additional applied patches and full kconfig is available on http://www.mygnu.de/index.php/2009/10/zen-sources-2-6-31-r1-with-tuxonice/. At least with my Adaptec SlimSCSI 1460 card it works without problems. So I would be glad if the "no 64 Bits" dependency could be removed in future kernels. Perhaps other drivers in the scsi-pcmcia section are also affected, but I cannot try these out since the aha152. best regards Jürgen
