At this point, the most likely candidate is a memory corruption
error, probably hardware. Can you run memtest86 for a few hours
to get a bit more confidence in the hw (preferably overnight)?

I did recently see another quite similar corruption in the
pagecache radix-tree, though. Coincidence maybe?

Those memories are new, but I can try. No problem. Will get back to
you by tomorrow.

I hope not.

I let it running at lunch time and all went OK. I've also let burnP6
running later and nothing happened. Looks like hw is OK.

I've just got another oops, with same kernel.

In the end, it was a motherboard issue.
