280 .Pp
281 Note that some

283 devices also have newer
284 .Tn ISA
285 Plug-and-Play variants.
286 These are listed in
287 .Xr isapnp 4 .
288 Some i386 platforms use
289 .Xr pnpbios 4
290 to attach
291 .Tn ISA
292 devices.
293 .Sh DIAGNOSTICS
294 .Bl -diag
295 .It "Stray interrupt on IRQ 7"
296 It means the interrupt controller reported an unmasked interrupt on IRQ
297 7, but no driver attached to that IRQ `claimed' it.
298 .Pp
299 There are two reasons this can happen:
300 .Bl -bullet
301 .It
302 In anything other than i386, it would almost always mean that there is a
303 driver attached to the IRQ, but it is the wrong driver.
304 .It
305 On i386, there is the more obscure issue of `default IRQ7's.
306 That is, when a device asserts an IRQ, but the IRQ is deasserted
307 after the PIC latches the interrupt and before the CPU acknowledges
308 it, the PIC just flat out lies about which IRQ it was.
309 It is usually due to a suboptimally coded driver.
