I have recently started seeing all sorts of weird instability on my power
mac. For instance, when trying to link sys/arch/macppc/stand/ofboot, I got:

ld -s -N -Ttext 6c0000 -Bstatic -o ofwboot  Locore.o boot.o ofdev.o net.o

cd'ing to the obj dir, I get:

i.e. what's supposed to be in net.o is in net.o and boot.o.

A while later, I got a kernel panic about freeing a free block (u/ffs
panic).

This is with both source and obj sitting on scsi disks on a bha card.

Next step is to try and back up the source to see if I can make it go
away.

Take care,
