<P>Abel,
|
|
<BR>
|
|
I forwarded the this post onto Juergen Fischer. Unfortunately
|
|
<BR>
|
|
I'm probably getting a bit confused between the aha152x
|
|
<BR>
|
|
[which is mainatined by Juergen] and the aha1542 [Eric
|
|
<BR>
|
|
Youngdale?].
|
|
<BR>
|
|
<P>Anyway, which kernel version are you testing? Where does that
|
|
<BR>
|
|
"--enable-scsibuffersize=32768" go (is it backend specific)?
|
|
<BR>
|
|
<P>I have a aha1542b, a UMAX 1220S and sane 1.0.2 installed.
|
|
<BR>
