Hi:

I have a Jaz 2GB drive which works fine on my
laptop running Red Hat 5.2 (using ppa).
I tried mounting the drive on my other PC
running Mandrake 6.1. When I type "modprobe ppa",
the machine freezes. [I have added the line
"alias scsi_adapter ppa" in my conf.modules file].

Here is the relevant part of the /var/log/messages
file:

++++++++++++++++++++++++++++

Dec 19 14:36:46 24 kernel: sda: Write Protect is off
+++++++++++++++++++++++++++++

This is where the machine freezes and where I have to use the
reset button (CRL+ALT+DEL will not work). [The next entry in
the /var/log/messages file is the restart line].

I normally have a printer connected to the parallel port,
but I have checked that the lp module was not loaded
before modprobing ppa.

I have made many attempts (also trying
using insmod in place of modprobe) but got nowhere. At one point
I got an extra error from modprobe:

Dec 19 15:02:00 24 modprobe: can't locate module block-major-8

Do I need a block-major line in conf.modules? Does the printer
have to be disabled with printtool as well?

Thanks in advance,

Serge Pineault
