Note that some

|
Plug-and-Play variants.

These are listed in

Some i386 platforms use

to attach

|
|
devices.
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "Stray interrupt on IRQ 7"
|
|
It means the interrupt controller reported an unmasked interrupt on IRQ
|
|
7, but no driver attached to that IRQ `claimed' it.
|
|
.Pp
|
|
There are two reasons this can happen:
|
|
.Bl -bullet
|
|
.It
|
|
In anything other than i386, it would almost always mean that there is a
|
|
driver attached to the IRQ, but it is the wrong driver.
|
|
.It
|
|
On i386, there is the more obscure issue of `default IRQ7's.
|
|
That is, when a device asserts an IRQ, but the IRQ is deasserted
|
|
after the PIC latches the interrupt and before the CPU acknowledges
|
|
it, the PIC just flat out lies about which IRQ it was.
|
|
It is usually due to a suboptimally coded driver.
