Well after many days and heaven alone knows how many hours, I'm beginning to go completely loopy. After getting a number of odd messages (as in above) I finally got the following:
debian/rules.d/4-checks.mk:12: recipe for target 'module-check-generic' failed make: *** [module-check-generic] Error 1 I tried a number of things like adjusting the HEAD, but nothing changed. So I figured I must have made a mistake somewhere and started again. More odd messages. Not wanting to go down that path again I tried playing a little with the bisect range, but all this showed was what I've always suspected - the problem lies between 4.3.0-7.18 and 4.4.0-1.15. When I try to bisect these to confirm, the 'debian.master' directory gets deleted, which appears to be because they are non-linear (whatever that means). Looking at the instructions, they get pretty vague here. Seems to me they are fine for straightforward things, but quite esoteric when things go awry. Is it telling me that I now need to commit bisect the mainline kernels? It mentions something about mapping one to the other, but this proved confusing and useless. I'd like some confirmation about this as all I really know where mainline kernels are concerned is that I have no problem at v4.3.6 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3.6-wily) and have a problem at v4.4-rc1+cod1 (http://kernel.ubuntu.com/~kernel- ppa/mainline/v4.4-rc1+cod1-wily). To be honest, I'm not even sure that posting here is the proper way to seek assistance (I'm starting to suspect it isn't in which case I'm really lost), but will attempt the mainline bisect if I here nothing. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1613027 Title: Network scanner not detected by xsane after upgrade to 16.04 Status in linux package in Ubuntu: Incomplete Bug description: Hopefully I'm reporting this in the correct area/group. Sorry if not. After upgrading to 16.04, my scanner is no longer detected by xsane (and other scan apps.) The model is 'Epson WF-3520' multi-function and is connected wirelessly to the network. The problem occurs on all my computers: A Dell 64 bit desktop, An Asus 64 bit laptop, A Medion 32 bit laptop. I've upgraded to the latest software released by the manufacturer on 2 computers, but it makes no difference. Printing works OK and also the scanner is detected if I connect using a USB cable (a second printer is installed though). The problem only occurs using the 'linux-image-4.4.0...' series of kernels. If I boot with any of the previous kernels available, 'linux-image-4.2.0...' or 'linux-image-3.19.0...' everything works OK. I am able to ping the scanner. I've tried a number of suggested fixes from searching around various forums, although many of these relate to 'back-end' scanners connected to a host for network access which is not applicable as mine is connected directly to the network. In any case none have worked. I have tried the following: . Removing all manufacturer software and /usr/sane.d/epkowa.conf . Comment out all entries in the /usr/sane.d/dll (Back-end related) . Comment out all entries in the /usr/sane.d/dll.conf.conf except 'net' and adding 'epkowa' (Back-end related) . Disable the firewall (ufw) . Specifically adding a port to use (1865) (ie. net 192.1... 1865 . Linking the libraries in /usr/lib/sane to /usr/lib/x86_64-linux-gnu/sane Other than that I'm at a loss and sticking with older kernels. Regards.
