I noticed this hang on udevadm settle too. I'm temporarily working around
it by adding udevtimeout=5 to the command line. I haven't looked into it any further.

On my system I bisected these constant change notifications to 929e27252e
'ide: ide_requeue_and_plug() reinstate "always plug" behaviour' [1] but
haven't looked any past that.

On my system, I'm not noticing anything strange here, but I'm not using the
CDROM drive:
]# cat /proc/interrupts | grep ide && sleep 3 && cat /proc/interrupts | grep ide
14: 100 43433 522 0 IO-APIC-edge ide0
15: 0 0 0 0 IO-APIC-edge ide1
14: 100 43469 522 0 IO-APIC-edge ide0
15: 0 0 0 0 IO-APIC-edge ide1
Cheers,
Shaun
