quik/kernel interaction

[Michel Lanners]

Hi Bill,

On   6 Aug, this message from Bill Jackson echoed through cyberspace:

Occasionally, I had the same problem, but it was relatively random. It
could happen on one kernel, I would recompile it, and the problem would
be gone. Or I switched the box off for some time, retried, and now it
worked...

I would rather conclude on some strange phenomenon rather than a
straight bug somewhere. Possibly recent kernels, due to some code
changes like differences in execution time, reveal the problem more
often....

Unfortunately, I don't have a solution neither.... Note that I'm running
aome old version of quik that I had to modifiy to get it to boot my G3
processor upgrade card. There was a problem with the way the BAT regs
were set... No idea whether the fix Paulus sent me actually made its way
into the latest quik release.
