| |
I have recently attached a Hewlett Packard ScanJet IIp SCSI scanner to my Adaptec 2842 VLB controller. I compiled the latest Linux kernel (as of today it is 1.3.79) and the scanner is recognized on boot-up as /dev/sgd.
The whole machine locks solid when accessing the scanner only solved by a cold boot. I have only tried one scanning program to access the scanner so far as there was only on which seemed to be made specifically for the hp scanner line. The program that I am using is hpscanpbm avaliable from sunsite:
http://sunsite.unc.edu/pub/Linux/apps/graphics/scanners/
file hpscanpbm-0.3a.tar.gz
It accesses the scanner, the scanner starts scanning then about half way accross the scanning bed the scanner stops and my machine locks solid.
My guess is that the problem is in either the program hpscanpbm, the kernel's generic SCSI code or the aha2842 SCSI deriver. I have not tried any of the older kernels (eg. 1.2.13).
I am not running the scan program SUID root and it still locks the machine so my guess is that it may not be the scanning program but may be either one of the other two possible code related areas.
Has any one else had experience with this or know of any fixes?
This is part of a larger project which our office is working on which will enable text-to-tape coversion in a Unix envoronment similar to Arkenstone's MS-Win based Openbook Unbound system but our version will be text based.
Here is the complete list of hardware:

Distribution:
Caldera 1.0 Release
Kernel: linux-1.3.79 compiled as ELF
