281Note that some 282.Tn ISA 283devices also have newer 284.Tn ISA 285Plug-and-Play variants. 286These are listed in 287.Xr isapnp 4 . 288Some i386 platforms use 289.Xr pnpbios 4 290to attach 291.Tn ISA 292devices. 293.Sh DIAGNOSTICS 294.Bl -diag 295.It "Stray interrupt on IRQ 7" 296It means the interrupt controller reported an unmasked interrupt on IRQ 2977, but no driver attached to that IRQ `claimed' it. 298.Pp 299There are two reasons this can happen: 300.Bl -bullet 301.It 302In anything other than i386, it would almost always mean that there is a 303driver attached to the IRQ, but it is the wrong driver. 304.It 305On i386, there is the more obscure issue of `default IRQ7's. 306That is, when a device asserts an IRQ, but the IRQ is deasserted 307after the PIC latches the interrupt and before the CPU acknowledges 308it, the PIC just flat out lies about which IRQ it was. 309It is usually due to a suboptimally coded driver. 310.El 311.El 312.Sh SEE ALSO 313.Xr adv 4 , 314.Xr aha 4
