Hello,
i've got some problems with the i2o subsystem for 2.6 kernel. The
i2o_scsi driver, which let access to the single disk's via the scsi
subsystems, works fine on 32-bit systems, but on 64-bit (AMD64), the
kernel panic...
Here is some logging output, which come from the i2o_scsi driver. On
32-bit, the following command
dd if=/dev/sda of=/tmp/foo bs=1 count=1
will result in one Scsi_Cmnd. Here is some logging output:

but if i run the same command on an 64-bit system, the output looks like:

i've hardcoded the sg_tablesize to 1 (because i thought it was the
source of the problem). But also with sg_tablesize = 4, the first three
messages disappear some how, and the fourth will be executed... I know
that the source of the problem is in the i2o_scsi driver, but maybe you
could help me, why there are so many more Scsi_Cmnd's? Any help, what
would be very appreciated.
Best regards,
Markus Lidel
