I have tried to build a more up to date kernel for my Fu Long computer with the 2.6.23-rc3 testing version, while it is currently running release 2.6.18.1. I tend to build my kernels with as many options as possible and most of them as modules if they are not necessary for booting. When I was building the latest testing version I got the following errors: > ERROR: "free_dma" [drivers/scsi/qlogicfas.ko] undefined! > ERROR: "free_dma" [drivers/scsi/pas16.ko] undefined! > ERROR: "free_dma" [drivers/scsi/NCR53c406a.ko] undefined! > ERROR: "request_dma" [drivers/net/tokenring/skisa.ko] undefined! > ERROR: "free_dma" [drivers/net/tokenring/skisa.ko] undefined! > ERROR: "request_dma" [drivers/net/tokenring/proteon.ko] undefined! > ERROR: "free_dma" [drivers/net/tokenring/proteon.ko] undefined! > ERROR: "__cmpdi2" [drivers/md/dm-snapshot.ko] undefined! > make[1]: *** [__modpost] Error 1 > make: *** [modules] Error 2 On the one hand I understand that things like Token Ring support don't make sense for this kind of hardware but I was still allowed to select it, so I did :-). On the other hand while SCSI and DM support are not really suitable for the current Fu Long system, they might be for derivative ones and successors in the near future so it should be possible to use this hardware and their drivers. I have also bothered the SPARC developers with a similar error message for my Sun E250 server. I only hope to be helpful here and to be able to contribute in the near future. Regards, Sunil
