This was not the only issue, but the first one.
Two more bits in the IOC_CTRL register were getting
set on j6k (vs A500):
D4 Disable 4-byte coalescing. Apperently could
result in 12 byte transfers (4 byte-lanes not
enabled on the second 8 byte transaction)
that "some devices don't tolerate".
Documentation doesn't list these devices.
DD Disable Distributed LMMIO coalescing.
Disables coalescing for all PIO MMIO transactions
to addresses below distributed LMMIO ranges.
Directed LMMIO and other GMMIO ranges
may still coalesce (e.g. graphics buffers usually
get a directed range).
Spew ran for an hour and managed to push 80+ GB
of data to 6 disks. I'll commit this change shortly.
Then I got ambitious and ran "make clean" and XFS panic'd.
I expect this is a different problem.
Same one I've seen before:
[ no backtrace :^( ]
Kernel Fault: Code=26 regs=000000006cd40c10 (Addr=00000000000000c8)
