Thanks for letting me know, that's saved me from a tedious morning of
testing. Though did you also have the A9 errata enabled?

BTW, I noticed the PL310 Cache ID reports RTL version 3, which doesn't
appear in the list of versions in cache-l2x0.h and doesn't match the TRM
shipped on the vexpress CD, which is for version 2 (r1p0).

Anyway, I'll test various Linux versions with the L2 cache removed from
device-tree to see if that reliably fixes things.
