Better to use the fixes to QEMU instead of working around its problems in the linux kernel sources :-) This thread has the QEMU fixes: https://lists.nongnu.org/archive/html/qemu-devel/2014-08/msg03224.html I have posted them a couple of times to the QEMU dev list, but no-one seems to pick them up. > http://cgit.openadk.org/cgi/cgit/openadk.git/tree/target/m68k/qemu-m68k/patches/4.0.5/m68k-coldfire-fec.patch > Without this one I get > qemu: hardware error: mcf_fec_read: Bad address 0x1c4 > ... > Abort Yes, you still need that.

Hmm, no, haven't seen that one. I'll try a run with qemu and see if I can see what is going on.

It is not plain vanilla, I am really sorry about this ugly bug report. I normally use an option to disable any external kernel patches, before reporting. I missed it this time. I have experimented with aufs4 kernel patches lately.

I don't have any compile (or runtime) problems with m5208evb_defconfig
on linux-4.0.5 either. That is close to what most people use with qemu.
What .config are you using?
