I tried it myself using local diod and cache=mmap. I get a similar
SIGBUS on instruction fetch again. Conclusion: as Bakul says, now
I'm debugging linux. Not going there, thanks.

Going further off-topic for 9fans, sorry:

I thought it would be clever to update the linux client to a newer
kernel (4.19 was the latest I could find for debian 9). That
didn't go well: booting the new kernel fails with the message
  Failed to find cpu0 device node

Does anyone know if it's feasible to do an out-of-tree build
of v9fs kernel modules (9p, 9pnet?) from current source [where
is it?] and use them with my old 4.9 kernel?
