Hi,
I own a dpt smart raid v (1554U2) scsi controller, for wich i used the dpt_i2o driver under kernel 2.4, wich is currently broken in 2.6. I googled a bit around, and found out that the suggested solution is to use use the i2o-scsi driver: http://marc.theaimsgroup.com/?l=linux-scsi&m=106046024506801&w=2 also see this thread: http://marc.theaimsgroup.com/?t=106191158100004&r=1&w=2
So i compiled a fresh 2.6.0-test11 kernel, and build i2o-core, i2o-proc, i2o-scsi and i2o-block as modules. While modprobing i2o-core without parameters it told me: "Skipping Adaptec/DPT I2O raid with preferred native driver." with "dpt=1" the module loads, but it complains that it cant get the size of the device:
-- Activating I2O controllers... This may take a few minutes if there are many devices i2o/iop0: LCT has 15 entries. i2o_scsi.c: Version 0.1.2 chain_pool: 2048 bytes @ df1a7800 (512 byte buffers X 4 can_queue X 1 i2o controllers) --> PARAMS_GET - Error: --> ErrorInfoSize = 0x01, BlockStatus = 0x08, BlockSize = 0x0002 scsi1 : i2o/iop0 Vendor: IBM Model: DDRS-39130W Rev: S97B Type: Direct-Access ANSI SCSI revision: 02 --> sda : READ CAPACITY failed. --> sda : status=0, message=00, host=7, driver=00 --> sda : sense not available.

in this state fdisk tells me the following:
-- Disk /dev/sda: 1073 MB, 1073741824 bytes 255 heads, 63 sectors/track, 130 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes

which is wrong, because the attached harddisk (i dont use the raid features of this controller) is an ibm ddrs-39130w -> size = 9.1 gb
on 2.4, using the dpt_i2o driver, i dont experience this problems:
