I tried to install FreeBSD 6.1-BETA4 on IBM x336 and it was not
booting. I googled a bit and I found this is known problem for this
platform:
http://docs.freebsd.org/cgi/mid.cgi?200510061556.55464.jhb
To make the system up and running, I had to disable APIC and force
keyboard to attach. Of course, I didn't like that. ;-)
The first thing I wanted to fix was:
acpi0: <IBM SERONYXP> on motherboard
acpi0: [MPSAFE]
pci_open(1): mode 1 addr port (0x0cf8) is 0x80000144
pci_open(1a): mode1res=0x80000000 (0x80000000)
pci_cfgcheck: device 0 [class=060000] [hdr=80] is there
(id=35908086)
acpi_bus_number: root bus has no _BBN, assuming 0
acpi_bus_number: can't get _ADR
acpi_bus_number: can't get _ADR
...
I added 'PNP0A08' to pcib_ids in src/sys/dev/acpica/acpi_pcib_acpi.c
because this system had this:
Scope (\_SB)
{
Device (PCI0)
{
Name (_HID, EisaId ("PNP0A08"))
Name (_CID, 0x030AD041)
...
This ID was added in ACPI 3.0 as 'PCI Express Root Bridge', instead of
'PNP0A03', which is PCI/PCI-X root bridge. However, I got something
like this instead:
acpi0: could not allocate interrupt
ACPI-0210: *** Error: Unable to install System Control Interrupt
Handler, AE_ALREADY_EXISTS
acpi0: Could not enable ACPI: AE_ALREADY_EXISTS
No driver was able to allocate IRQ after this and I am quite puzzled
right now. Is it correct thing to do? Why does it break? Why can't
I install SCI handler?
