When I initially saw Rohit's post I thought when he said "scsi support has been compiled into the kernel" he meant that it was compiled in as opposed to being a module. Then people posted telling him it couldn't be done in a module without an initrd. Then we got into a debate about the advantages and disadvantages of initrd vs compiling into the kernel (non module). Putting aside the initrd/compile in argument, it seems that something is either missing from Rhit's kernel or from his initrd. Its likely to be the low level scsi driver for his chipset. Possibly this would have been sorted earlier if Rohit had (a) clarified what he meant by "compiled in" and (b) told us exactly what scsi stuff was included in his kernel config file. -- Nick Rout
