I just replaced my -current with an I815EP mother board and found that the mouse and
printer not
working. When I was moving the mouse, the cursor on the console just disappeared and
reappeared
after I stop moving the mouse. For the printer port, when I sent some data, the
printer's data
LED was flashing, indicating data was received, but it never printed anything.
I stopped loading ACPI at boot and everything become normal. I did have some good
experience with
this motherboard and ACPI several months ago so I searched back and found that the
following
commit caused the problem

In particular this patch causes my problem:
@@ -461,9 +460,9 @@ acpi_pci_link_add_prt(device_t pcidev, A
return_ACPI_STATUS (error);
}
- if (!(sta & ACPI_STA_ENABLE)) {
+ if (!(sta & (ACPI_STA_PRESENT | ACPI_STA_FUNCTIONAL))) {
ACPI_DEBUG_PRINT((ACPI_DB_ERROR,
- "PCI interrupt link is disabled - %s\n",
+ "PCI interrupt link is not functional - %s\n",
acpi_name(handle)));
return_ACPI_STATUS (AE_ERROR);
}
I believe it was related to the interrupt handling as you can see on the following
output from
"vmstat -i"
"vmstat -i" for a problematic mouse/printer config (note: no psm0 irq12)
interrupt total rate
stray irq0 1 0

Any idea on this one?
