As doctor said theres not enough, my suggestion was to focus on the area where the error is occurring, and
in some ways I think you may have some of that, but perhaps there's a little more that will help, perhaps there's nothing more usful in there
back to what Doctor mentioned about power, could be correct, even if it was working under mageia 5.
it could be its just on its limits.
there are many
#
ioctl(11, USBDEVFS_REAPURBNDELAY, 0x7ffe02c9b698) = -1 EAGAIN (Resource temporarily unavailable)
which is the hardware read/write of the usb device
entries in the above suggesting its failing to communicate with the scanner intermittently
it clearly opens /root/.sane/canon-lide-120.cal
stats it
then writes to it, a fare amount of data.
before finally closing the file.
it then shuts down the usb device, and during the unmapping of the device from memory tries and tries several times before giving up and core dumping.
so this does suggest a device that keeps going offline, intermittently and it could be that its power is on the limits.
id suggest trying with a powered usb hub.
ive learned from experience that when buying usb things that are potentially hungry on power to make sure they are independently powered.
my scanner is, and so are any of the usb harddisks.
