Surely some broken hardware, but not necesarily someone at IRQ 7.

IRQ 7 is the "last option" for the interrupt controller.  It's used
when a interrupt has happened but it does not know which.

Everytime this happened to me it was a cheap and faulty IDE controller,
but I think an older parallel port can also generate this.
