Which compiler flag do you use? Do you use GENERIC? Then, it is
compiled with -m68020-60 by arch/m68k/Makefile.cmachflags...
I use a mostly stripped down GENERIC, but no change to CPU flags.
So yes, it is built with -m68020-60.
Or emulator accepts some kinds of instructions that do not work on
I don't think so. But it doesn't emulate caches and the TLB works
Thank you for your comments! I understand the situation.
Saying that, after a few hours idling in multi-user, the system
paniced with an uvm_fault followed by an illegal instruction
trap. Neither looked real in DDB.
I'll have to retry this with a gcc7-built kernel, it could be
some other m68k instability introduced in -current.
Hmm, for my A1200, a GCC7-buit kernel as of last week works without
problems at least for several days. So, it can be due to GCC8.
