Well, I have two Acorn RiscPC 600's. One with a strongarm, which runs up-to-date
-current with no problems(well done the team!), but I also have one with it's
original arm610 which hasn't been able to boot a -current kernel since October,
and I had to do some kludging to make one work then. The kludges no longer work.

I believe Mark Brinicombe is working on this, but I don't know if any progress has
been made. I have pinned down the problem to a call to setttb() during the
secondary bootstrap. There is no return from this call and, since it's arm
assembler(cpufuncs.S IIRC) which might as well be martian to me, I can't really
pin it down any closer than that.

The first call to setttb() during the primary bootstrap returns fine.

Make it idiot-proof and someone will make a better idiot!
