This is unrelated to Tony's original "unaligned access" problem, right?
If I understand correctly, you have CONFIG_DEBUG_SLAB turned on, and
it reported a double free in the pci_acpi_scan_root() path in the rc2
kernel. Then you tried rc3 and saw a similar slab problem in
the acpi_sba_ioc_add() path.
I looked at both of those paths, and I don't see anything wrong. I
tried unsuccessfully to reproduce it with an rc1-mm4 kernel on an
rx2600. I also tried an rc3 kernel (hg pull from 10 minutes ago)
and couldn't reproduce it.
You have ACPI debug stuff turned on, don't you? I didn't enable that.
Can you reproduce the slab problem with that turned off?
