Modified Files:
        src/sys/dev/acpi: acpi_pci_link.c

Log Message:
re-enable the code to disable link devices at startup, ie. revert rev 1.3.
this fixes PCI interrupts on some systems (eg. HP XW9400) and we suspect that
the problems which led to the original change were caused by buggy early
implementations of ACPI, which are now ignored by date.

To generate a diff of this commit:
cvs rdiff -u -r1.18 -r1.19 src/sys/dev/acpi/acpi_pci_link.c
Sorry to test this late: one of my test systems is affected by this and does
not boot with r1.19 any more.

It is not exactly new, but neither old enough to have ACPI ignored:

TYAN Computer Corp. S2895 (TYAN Thunder K8WE S2895)
acpi0 at mainbus0: Intel ACPICA 20110623
acpi0: X/RSDT: OemId <PTLTD ,  RSDT  ,06040000>, AslId < LTP,00000000>
acpi0: SCI interrupting at int 9

If anyone needs acpi dumps, let me know off-list.


Do we need quirks or something for this sort of thing? Unfortunately, this change was just pulled up to netbsd-6-0. (and -6) :/
