I tried AM53C974 but it didn't make any difference.<br>
|
||
This PC is a plain Pentium-133, with an Asus PC97-V mainboard (with<br>
|
||
integrated VGA card), 32MB RAM, a PCI NE-2000 Ethernet card set to<br>
|
||
"Jumperless, Interrupt:10, Address:0x300" and a Tekram DC-390 PCI SCSI<br>
|
||
card set to "address: 0xb800; irq: 11".<br>
|
||
Nothing else is installed. Usually this PC is used for CD-ROM burning<br>
|
||
under Linux and it works. Kernel is 2.0.29.<br>
|
||
<p>
|
||
I now tried to remove the internal SCSI CD-R (so scanner is alone), but<br>
|
||
still no success.<br>
|
||
<p>
|
||
When I start the SCSI AM53C974 module, the scanner is immediately<br>
|
||
detected:<br>
|
||
<p>
|
||
cat /proc/scsi/scsi<br>
|
||
<p>
|
||
Attached devices: <br>
|
||
Host: scsi0 Channel: 00 Id: 04 Lun: 00<br>
|
||
Vendor: Model: Scanner 636A4 Rev: 1.00<br>
|
||
Type: Scanner ANSI SCSI revision: 02<br>
|
||
<p>
|
||
Then I try to scan with xscanimage. <br>
|
||
The scanner usually does some steps in order to acquire an image: first<br>
|
||
the scanner head moves quickcly for about 2 seconds around its rest<br>
|
||
position (something like an initialization), then it sits silent for 1<br>
|
||
second and finally the real scan begins. <br>
|
||
With this PC with DC-390, it does only the initialization part, then<br>
|
||
SCSI bus is locked.<br>
|
||
Computer and all its peripherials work correctly.<br>
|
||
<p>
|
||
After quite a while (some minutes), periodically the following message<br>
|
||
appears on console and syslog:<br>
|
||
