FreeBSD Port: graphics/sane-backends

[Charles Ziegler]

Hi,

On my "FreeBSD Dad 10.2-RELEASE-p12 FreeBSD 10.2-RELEASE-p12 #0: Tue Feb
23 18:14:09 EST 2016     chuck at Dad:/usr/obj/usr/src/sys/DEBUG_ATA
amd64" system, xsane, gscan2pdf, and scanimage -L would cause the
following warnings to appear on the console.

ata2: FAILURE - odd-sized DMA transfer attempt 5 % 2
ata2: setting up DMA failed
ata2: FAILURE - odd-sized DMA transfer attempt 5 % 2
ata2: setting up DMA failed
ata2: FAILURE - odd-sized DMA transfer attempt 5 % 2
ata2: setting up DMA failed
ata2: FAILURE - odd-sized DMA transfer attempt 5 % 2
ata2: setting up DMA failed
ata4: already running!

Once they appeared reads and writes to the hard drive no longer worked
rendering the system unusable.

The microtek2 backend is responsible for the "ata2: FAILURE - odd-sized
DMA transfer attempt 5 % 2" and the microtek backend appears to be
responsible for the "ata4: already running!".

These warnings went away and the system appears to operate normally
after commenting out microtek and microtek2 out in
"usr/local/etc/sane.d/dll.conf" file.

Please reference bug 207431 on bugs.freebsd.org.

Note: DEBUG_ATA is the generic kernel with options CAMDEBUG.

Best Regards,
