[sane-devel] Microtek V6USL: out of memory

[Patrick S. Leung]

Hi Erik,

I retired using your recommendation and it doesn't help much.  Looks 
like the SANEI_DEBUG_SANEI_SCSI doesn't produces much output, but I do 
see some low level in /var/log/message ( I did a tail -f 
/var/log/message before I start sane):

Apr 5 13:23:49 localhost kernel:  __alloc_pages: 3-order allocation failed.
Apr 5 13:23:49 localhost kernel:  __alloc_pages: 2-order allocation failed.
 Last message repeat many times


I don't know if this have anything to do with sane.

Here is the environment:

SANEI_DEBUG_SANEI_SCSI=255
SANE_DEBUG_MICROTEK2=255
SANE_DEFAULT_DEVICE=/dev/sg5
SANE_SG_BUFFERSIZE=32768

Here is the debug output again:
====================================================================
