Along with the lockups already described here, I've noticed an
unidentified source of interrupts on IRQ7.


I wonder if people experiencing lockup problems also have these
noise interrupts,

I just took a look at this, by setting up parport_pc, and yes I get noise.

This was my first sample with a kernel with APIC:
7: 29230 IO-APIC-edge parport0

I just did an experminent with a very light kernel, nearly nothing compiled inside, except apic acpi, preempt and needed stuff plus scsi+libata and no ide. IRQ 7 was not present and every device had its own irq. Nevertheless system locked up at second hdparm run...
