Sorry for the delay. Our main machine, 'muta', has been suffering
instability for a while. It ended up also having bad RAM and failing
disks. We've now replaced them last night.

We had a lot of kernel crashes since then but after upgrading to
6.10.11, everything seems okay so far. Fingers crossed, and then I can
get back to the other bits (like testing the binutils patch).

(The panics were all in pte_offset_map_nolock.)
