I have an IBM Thinkpad(T21) with an Adaptec 1480 card. I am running a 2.4.2 kernel. I can use the 1480 fine if I boot from the internal IDE drive but I am trying to build a boot floppy which will use an initrd then boot from the scsi disk on the 1480.
When I boot using the initrd the AIC7xxx driver loads OK but it doesn't find the disk and then I get a kernel Panic because there ain't no root partition.
Output is below. Note the point where the output stops using the initrd and the nornal output when I am booting from the IDE root partition.
I think I have all the right modules in the initrd.
