OK, I applied the patch and tried setting
hw.pci.link.LNKB.irq=10
hw.pci.link.LNKD.irq=10
hw.pci.link.LNKF.irq=10
As you suggested, but no luck:
a) Only IRQ's set as above in loader.conf:
85% interrupt, surprisingly, the usb stick appears fast and mounts fast,
but the system is slow: I tried timing make on the acpi kernel module,
after 7 minutes it hadn't finished.
b) As above but pci_link disabled:
>85% interrupt, and trying to get out of top crashed the system.
c) As a) but with apic disabled:
Won't boot: hangs when kernel finish identifying devices, sometimes
before. ACPI errors:
ACPI-0800 AcpiEvGpeDispatch No handler or method for GPE[ 6] disabling
event
d) b+c:
USB stick is found after significant amount of time and won't mount.
The dmesg etc are here http://www.locolomo.org/src/acpi/, all with the
keyword "patch" in the file name.
:(
Looking at the dmesg's something seems to be going on on usb2:
rr232x: no controller detected.
ACPI-0800: *** Error: AcpiEvGpeDispatch: No handler or method for
GPE[ 6], disabling event
ACPI-0800: *** Error: AcpiEvGpeDispatch: No handler or method for

ACPI-0800: *** Error: AcpiEvGpeDispatch: No handler or method for

usb2: host controller process error
usb2: host controller halted
acpi_acad0: acline initialization start
which occurs when pci_link is enabled w/wo apic.
When both apic and pci_link are disabled, I find this line:
rr232x: no controller detected.
Interrupt storm detected on "irq9:"; throttling interrupt source
acpi_acad0: acline initialization start
When apic is disabled the IRQ's change (which is to be expected I
guess?) the range 16-23 is no longer used. In that case I found
uhci1/usb1 assigned irq 9 but it is uhci2/usb2 which is routed to irq 3
that fails.
??
Thanks, Erik
