Hi,

please try to download version 0.72 of the hp-backend from
http://www.kirchgessner.net along with another patch available
on that page. The backend has a bug-fix which caused
a segmentation fault.
But I am quite sure that this does not solve the problem.
scanimage and xscanimage are application programs which should
never cause the system to crash. The program make crash itself.
But if the system crashes, it might be a problem with the systems
SCSI driver.
