|

|
|
<P>At least I found out that the first error is due
|
|||
|
|
<BR>
|
|||
|
|
to a unpatched call to scsi_cmd in unit_ready which
|
|||
|
|
<BR>
|
|||
|
|
is still using the parameters of the unpatched scsi_cmd
|
|||
|
|
<BR>
|
|||
|
|
function. I think, this must be a solaris thing because of
|
|||
|
|
<BR>
|
|||
|
|
this block of code is enclosed in #if USE == SOLARIS_INTERFACE,
|
|||
|
|
<BR>
|
|||
|
|
so you won't get in touch with this under Linux or so, but I
|
|||
|
|
<BR>
|
|||
|
|
should better consign the analysis to the professionals :-)
