Package: sane-utils
Version: 1.0.19~cvs20070730-1
Severity: important
Using microtek2 backend via parallel port, ppscsi 0.92 and onscsi 0.91,
scanning with low resolution, i.e. 75 px/inch, works o.k. in scanimage
and preview works o.k. in xscanimage. Full resolution (300 px/inch)
fails. The scanner positions the head but transfers no data, scanimage
exits with EOF, (xscanimage locks up), scanner power off/on is the only
recovery. This is a new failure with kernel 2.6.18 -- all functions
worked normally with previous kernel 2.6.8
I have /proc/scsi/sg/def_reserved_size=130560.
with export SANE_DEBUG_MICROTEK2=255
export SANE_DEBUG_SANEI_SCSI=255
and option=2 in microtek2.conf
Here is the tail end of the debug output beginning just before the point
where the high resolution (failing) scan differs from the low resolution
(successful) scan.
[I have debug files captured at 75 px/inch and 300 px/inch as well as
good scans at 300 px/inch in kernel 2.6.8 but they are BIG files available
on request. Also saved the relevant kern.log messages from onscsi.]
