I just rebooted on an August 11 kernel. My system
still is happy with the disks. Hmm.
I can't remember exactly where my tracing went, before I
left off before, but the message you are seeing comes from
/sys/i386/isa/diskslice_machdep.c, line 200 (version 1.35).
What you will probably find, is that if you put a line that
instead of "goto done", you will find that, on the second
attempt, it reads the mbr successfully.
The above is a severe kludge, and that is why I never committed
any code to do anything of the sort. I think the error is
actually somewhere in the ATA code (sorry Soren). I don't
want to patch around a bug.
Now somebody remarked that after the probe, a drive status
light stayed on - maybe, the probe is not doing something
properly for some drives, or there is somethign timing out.
